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.

Dr. Peter O’Brien is head of the Photonics Packaging Group at the Tyndall National Institute, University College Cork, Ireland. He is also Deputy Director of the Science Foundation Ireland-Irish Photonics Integration Centre. Since establishing the Photonics Packaging Group in 2009, Dr. O’Brien has built a research team who address challenges in the area of highly integrated photonic devices for applications in communications, biomedical devices and sensors.
His group has developed a range of photonic packaging technologies which have been made available to users worldwide through a foundry service in collaboration with IMEC.

They have also prepared a range of packaging design rules, which have recently been implemented in PIC design tools such as those available through Phoenix Software and Luceda Photonics.

These design rules provide valuable guidance to PIC designers, ensuring their photonic devices are compatible with standard packaging technologies. The group has established research collaborations with institutes including UC Berkeley, University of Arizona, CERN, IMEC, CEA-LETI and Fraunhofer Heinrich-Hertz.

 


peterDr. O’Brien received a degree in Physics from Trinity College Dublin, and a Masters and PhD in Physics from University College Cork. He was a postdoctoral researcher at the California Institute of Technology and a research scientist at NASA’s Jet Propulsion Laboratory in Pasadena, where he was involved in the development of submillimeter wave devices for imaging and sensing applications. Dr O’Brien also founded a photonics company specializing in the development of bio-imaging systems, which he sold in 2009.

Monia Ghobadi is a postdoc at Microsoft Research. Her research interests are broadly in systems and networking, with recent focus on optical networking and congestion control. She received her PhD from University of Toronto and worked at Google’s data center team before joining Microsoft Research.

Abstract

To keep pace with the tremendous bandwidth growth in cloud networking, large scale proviers, such as Microsoft, employ optical technologies ubiquitously.  In fact, Microsoft’s long haul network carries hundreds of Tbps of data using optical links, and in its data center networks, all switch-to-switch links are optical.  Despite their almost-ubiquitous presence, little is known today about even basic characteristics (e.g., signal power, attenuation) opical links in such networks.

We conduct one of the first large-scale study of the optical layer of long haul and data center networks.  Our analysis uncovers several findings that can help improve network planning, increase capacity, and reduce transceiver cost.  In long haul networks, we find that substantial gain can be achieved using bandwidth variable transponders and changes in Q-factor can predict future optical-layer outages.  In data center networks, we find that the optical layer is significantly over-engineered in terms of optical power budget and monitoring optical layer metrics can lead to faster mitigation of packet corruption.

Inaugural O-RETinas Summer Program Success

CIAN is excited to announce completion of the first summer of the Optics Research Experience for Teachers in Native American Schools (O-RETinas) Research Experience for Teachers (RET) summer program.

This innovative program program hosted four teachers during the 2016 summer in a variety of research labs in optics, engineering, and chemistry as well as invited them to participate in an industry practicum. The teachers not only performed a guided research project in an innovative research laboratory but they also learned about industry applications, took a course at the University of Arizona, and participated in a number of culturally related workshops.

CIAN will continue the O-RETinas program in Summer 2017. Visit the website to learn more about how to apply!

CIAN is seeking additional industry mentors for the future O-RETinas programs. If you believe your company would be interested in hosting a teacher, please contact us!

Dr. Chris Chase
Bandwidth10, Inc.

 

Christopher Chase received his B. E. E. degree from the University of Minnesota-Twin Cities in 2005 in Electrical Engineering and a Ph.D. from U.C. Berkeley in 2011 in Electrical Engineering. He investigated high contrast grating integration in tunable and long wavelength VCSELs in his dissertation research. He has spent the last 5 years at Bandwidth10 in Berkeley, CA developing tunable VCSEL products for optical network and sensor applications.

Abstract

Low cost tunable lasers are a key component for the implementation of next generation optical access networks. The lack of a commercially available, low-cost tunable transceiver has hindered the implementation of higher speed, WDM (wavelength division multiplexed) capable access networks. In this talk, we will present Bandwidth10’s work implementing tunable VCSELs with high contrast gratings, achieving ~25 nm mechanical tuning range and over 3 mW output power. Error-free operation of an optical link using directly-modulated tunable VCSEL-based transceivers transmitting at 10 Gbps over 16 channels and transmitted over 10 km of single mode fiber is demonstrated, showing the suitability of the HCG tunable VCSEL as a low cost source for next generation WDM communications systems in access networks.
