OIDA 2017 Conference & Poster Competition

The recent OIDA/CIAN Workshop sponsored by IPIC and Go!Foton on March 19th, in Los Angeles, CA was a success!

The workshop was targeted at companies and innovators considering or already investing in integrated photonics to meet their future product requirements, and who need to understand key manufacturing challenges and how they can be addressed. Read more about the conference.
Key questions addressed included:

  • What supply chain, manufacturing, and packaging challenges are common across applications?
  • What common or standardized elements exist across applications?
  • What resources are available and how can gaps be filled?

Also during the conference a poster judging competition took place. Three top posters were selected as winners.

Project Abstract

Silicon photonic waveguides are typically designed to operate with the fundamental mode due to low cross talk with higher order modes and low propagation loss. However, currently, silicon photonics is being exploited for operation with higher order modes propagation for mode-division multiplexing (MDM).  This approach utilizes the orthogonal modes of a waveguide by encoding information both in space and wavelength to augment bandwidth limited wavelength-division multiplexing (WDM) systems. Conventionally, ring resonators and grating structures are applied to achieve spatial modes conversion. In this paper, we explore an alternative approach to mode conversion using counter-directional resonators. We introduce a cavity into grating-assisted directional couplers, offering both flexibility in design and wavelength selectivity provided by resonant structures. Our compact (54.5 μm2) device is demonstrated experimentally to operate with resonant 1st and 2nd order guided TE-modes.

From the Winner

OIDA was a chance for me to visualize the hurdles that photonic startups are meeting. I learned about the opportunities that exist to bring a product to market and the prices associated with these products.

2nd Place Winner

Peter Weigel
University of California, San Diego

Project Abstract

This research focuses on bringing lithium niobate films-on-insulator (LNOI) to the foundry-fabricated silicon-on-insulator (SOI) platform. This is done by fabricating bonded SOI-LNOI integrated devices, mitigating thermal stresses in the bonded stack to allow for standard fabrication procedures, and creating a fully functioning PDK of hybrid Si-LN optical device components for third party users. This technology enables compact devices in LN and highly efficient nonlinear optical devices based in Si, both of which are unattainable with each standalone bulk material platform.

From the Winner

The OIDA workshop at OFC 2017 was an exceptional opportunity to hear of the different routes researchers in academia and industry are currently taking to grow integrated photonics from a low-production, manually-intensive industry into something akin to the booming industry that integrated electronics has been for the last five decades. I left the workshop with a feeling of profound fortune to have the chance to work in a field with such impressive men and women.

3rd Place Winner

Alexander Gazman
Columbia University

Project Abstract

This research is focused on developing silicon photonic subsystems for high-performance computers and data-center applications. To be able to integrate the silicon photonic technology and utilize its functionality, software-defined control planes ought to reconfigure their operation based on the network needs. Previously we developed a subsystem consisting of a fast tunable laser and a silicon photonic chip operating as a demultiplexer. The demonstrated FPGA-based controlled plane allowed the user to choose a desired wavelength of operation and spatial switching: unicast, multicast or broadcast. In the presented work at the OIDA we added another layer of a feedback control ensure thermal stability of our subsystem.

From the Winner

The industry speakers broaden my view on their take on the silicon photonic technology. Additional applications were presented along with commercialization challenges.

Defining Your Audience:
Formal Presentations, Elevator Pitches and Developing Your Brand
By Bri McWhorter

No matter where you are presenting your ideas, whether it is in a formal presentation, an elevator pitch or developing your brand, you need to think about your audience first. How you craft and deliver your message depends on who you are speaking to.

 1. Presentation

Think about what type of audience you will be addressing. Are they a technical audience or a general one? What type of jargon is appropriate? How much detail can you go into? Knowing these answers will help you develop and organize your message.

Once you have that message, you have to think about the best way to deliver it. Focus on telling your story, rather than reiterating facts. Tell the audience why they should care about your research. Get them invested in the process.

2. Elevator Pitch

In an elevator pitch, you have a very small window of time where you have to capture your audience’s attention. Have a few pitches ready depending on whom you are talking to. That way, once you know a bit about their background, you can jump into the pitch that best fits the situation.

However, it isn’t enough to have different ideas of pitches, you need to workshop them. Practice with people from different backgrounds. See what works and what doesn’t. Then adjust your message depending on that feedback. It would be a shame to miss an opportunity to connect with someone because you didn’t take the time to work on perfecting your pitches.

3. Developing Your Brand

Knowing who your target audience is will help you decide which social media platforms to utilize. There are so many options available and it can be a bit overwhelming when you are starting out. For example, if you are trying to target young millennials, Snapchat is a good place to start. However, if you are trying to reach experts in your industry, I would suggest utilizing LinkedIn first, so you can establish a larger professional network.

Once you decide who you want to target, start connecting with people. Engage with posts they’ve written. Share your own ideas by writing articles. Establish your voice and take advantage of every networking opportunity that social media provides.

Summary

During a presentation, a pitch, or building your brand, always think about your audience first. Craft your goal by thinking about things from their perspective. This will help you create, distil and deliver your message in the most effective way.

Lumerical hosts Webinar

web_lcml-feb2017Recently, photonic design methodologies incorporating mature electronic design automation (EDA) software with optical design and simulation tools have emerged to support reliable photonic integrated circuit (PIC) design. Critical to any of these design methodologies is a Process Design Kit (PDK). The PDK provides the required fundamental information to produce a design based on a specific foundry process, from component geometries and cells for layout, to design rules, process variability data and simulation models. Essential to first-time-right designs, and the foundation of reliable fabless design methodologies for PICs is the inclusion of a calibrated photonic compact model library (CML) in the photonic PDK. The photonic CML enables a separation of component design from circuit design where PIC designers can scale complexity and optimize circuit performance and yield, confident that the underlying component geometry, material composition, and component design physics are represented by the CML, thereby ensuring reliable fabrication and predictable operation of their designs.

Lumerical’s suite of photonic design tools provides an infrastructure that supports the development and distribution of CMLs for PIC simulation and design. Typically, a CML is built upon a combination of accurate component-level simulation results and experimentally measured data. Lumerical works with leading integrated photonics foundries and researchers to develop modeling methods and libraries of the most advanced integrated photonics components.

We are hosting a complimentary webinar to introduce the Lumerical Compact Model Library (LCML), a reference library of common photonic elements and corresponding model development workflows. The webinar will show users how the LCML can be used to:

  • develop foundry-calibrated models for Process Design Kits (PDKs);
  • develop custom components and models for internal libraries;
  • and, design innovative photonic circuits and systems.

Two sessions will be held on February 7, 2017. Complete session details, as well as registration information, can be found here: https://www.lumerical.com/support/webinar/intro_lcml.html

To evaluate Lumerical simulation products, visit our Download Center and register for a 30-day trial.

As a photonic simulation software provider, Lumerical develops tools which enable product designers to understand light, and predict how it behaves within complex structures, circuits, and systems. Our current simulation software suite offers optical (FDTD Solutions, MODE Solutions), electrical (DEVICE CT), and thermal (DEVICE HT) simulation for component design, as well as circuit simulation for system design (INTERCONNECT).

rajatRajat Sharma
Ph.D. Candidate
University of California, San Diego

Rajat is a 4th year PhD student working with Prof. Shaya Fainman at the Department of Electrical and Computer Engineering at UCSD. The main focus of his research is engineering nonlinearities in silicon. He graduated with a B.S and M.S in Electrical Engineering, with a specialization in microelectronics and VLSI, from the Indian Institute of Technology (IIT) Madras in 2012.

Abstract

Starting from our past-experience in studying the linear electro-optic properties of strained-silicon waveguides, we carry forth a detailed analysis of various mechanisms contributing towards the exhibited (apparent) nonlinearity. We show, both theoretically and experimentally, that the bulk of the linear electro-optic response exhibited by such waveguides can be accounted for by the so-called free-carrier, capacitive, plasma-dispersion effect. The nature (magnitude and sign) of this effect is then shown to be critically dependent on the fixed-charges that are induced on the interface between a semiconductor and a dielectric. As such, this study becomes relevant and must be taken into account, not just for silicon waveguides, but all semiconductor waveguides. The range of tunability of both the real and imaginary part of the refractive index is measured and reported, the knowledge of which can be used in desigining high-efficiency silicon-slot capacitive modulators as well as low-loss passive devices. Furthermore, in our investigations, we find that commonly used clads (in strained silicon waveguides) like silicon nitride (SiNx) can exhibit bulk second-order nonlinearity. This is demonstrated via both free-space and in-waveguide measurements and a coefficient as high as 2.23 pm/V is reported for the case of the as-deposted PECVD SiNx. This value, though small, serves as a starting point in our efforts towards leveraging the SiNx platform for on-chip modulation and nonlinear wavemixing. The value of the exhibited coefficient can be enhanced manifolds by either shifting to non-stoichiometric silicon rich nitride (SRN) and or using SiNx in a slot configuration  with silicon and utilizing the electric field induced second harmonic effect (EFISH).

O’Brien Brings Advanced Packaging Research to CIAN

Dr. Peter O’Brien was recently appointed as an Adjunct Professor at the College of Optical Science at the University of Arizona. Dr. O’Brien brings expertise across a wide range of photonic packaging and integration technologies to CIAN, enabling advanced photonic devices to be packaged into fully working prototypes. Although his appointment only started in late 2015, collaborations between Dr. O’Brien and CIAN researchers are already producing results. For example, Dr. O’Brien has collaborated with Prof. Ming Wu and his postdoctoral researcher Dr. Tae Joon Seok to demonstrate packaging of UC Berkeley’s MEMs optical switch.

This enabled a fully packaged device to be tested in systems experiments performed by Prof. George Papen at UCSD. Results from this collaboration were presented at CIAN’s annual review in Columbia University last May, and a paper about this work will be presented at the IEEE Photonics Conference (IPC) in October. Further collaborations have started with Prof. Keren Bregman (Columbia) and Prof. Robert Norwood (Arizona), and it is expected that new collaborations will start over the coming months.
