PIC Designer Opening in Keysight Labs

Keysight Technologies

The PIC Designer position with Keysight Labs was created because the company views photonic integrated circuits as an important emerging technology—both in terms of its impact on the markets and because of its potentially revolutionary impact on measurement solutions.  This is a special position for a number of reasons:

  1. It offers a great environment for technical and professional growth.
  2. Keysight labs expects to cultivate academic contacts through collaborations, journal publications, etc.
  3. The position calls for guidance and leadership in identifying the most impactful technology applications of PICs—and in identifying the most compelling measurement opportunities.
  4. If the research is successful, the concepts and designs developed by the researcher can become commercialized in Kesight’s next-generation instruments.

The position is a “campus hire” position and is aimed at new Ph.D. or post-docs who are within 18 months of leaving the academic setting.

“Electro-optic Polymers and Their Role in Silicon Photonics”


Recently, we have witnessed the increased pervasiveness of information technologies and the explosion of wireless devices and streaming technology.  Internet networks and large data centers must continually increase capacity to keep up with our growing demand for data.  In 2013, the Internet carried on the order of 60 exabytes (1018 bytes) of information per month.  To put that into perspective, consider that the total text, audio and video output of humanity up to the year 2000 is estimated to have been about 12 exabytes.  It is clear that a multi-pronged technology development program is needed that continues to ride the success of microprocessor technology, while using photonics technology to provide both transmission and limited processing functionalities.  Major advances in organic photonics could help us keep up with the data explosion—namely, by deploying commercialized electro-optic (EO) polymers with high thermal- and photostability.  New materials in beta testing can reach between 200 and 250 pm/V, which is eight times larger than the benchmark material, lithium niobate.  EO polymers have long been valued for their intrinsically high bandwidths —reaching well into the hundreds of gigahertz and beyond.  This high bandwidth derives from the origin of EO polymer nonlinearity—virtual excitations of -conjugated electrons.  The combination of high EO coefficients, low dielectric constant, and ease of fabrication puts present generation EO polymers on excellent footing with respect to other EO materials, enabling the design and fabrication of high performance modulators with low drive voltages (0.5 – 2.5V).    It is also feasible to design and fabricate ultracompact modulators that can be easily integrated with silicon photonics.   Silicon is an increasingly important platform poised to revolutionize data center and computer interconnections the way that optical components such as amplifiers, dense wavelength division multiplexing filters, and wavelength-selective switches have transformed the fiber-optic core of the Internet.  We will review recent progress in EO polymers and discuss fundamental considerations concerning their use on the silicon photonics platform for improved modulation, switching,  and tunable filtering among other critical optical network functions.

Girls GoTech outreach by CIAN members at UC Berkeley

On Jan. 25th 2014, the association of WICSE (Women in CS and EE) at UC Berkeley participated in a Girl Scouts event at the Girls Go Tech & Green conference. The conference invited professional women scientists and engineers to present several workshops in different areas, aiming to encourage middle school and high school girls to step into the field of STEM (science, technology, engineering, and math).   

Being supported by the OSA student chapter at Berkeley – PhotoBears, where all CIAN students at Berkeley are involved, I hosted the optics demonstrations as a part of our workshop “Putting Science to Work” with 24 middle school girls involved.

Microrings as filters

In an earlier post I discussed how laser light is brought into waveguides on a chip. Now let’s look at some of the reasons we want to have light guided on chips in the first place. One device that shows the advantage of integrated optics is the ring resonator. It is a very compact device which allows precise discrimination of wavelengths.

On-chip coupling using gratings

When we think about guided optics or photonics, we usually think about two methods of guiding light: fiber optics and integrated optics. If you aren’t very familiar with guided light, here is a great introduction to get you started. Fiber optics has long been an important technology for telecommunications, and integrated optics has recently become an intense topic of research due to its promise of guiding light on silicon chips alongside microelectronics for purposes of increasing bandwidth, among other applications. But what about the interface between these two platforms? Continue reading
