Franiece Bennett Awarded CIAN Diversity Fellowship

CIAN student Franiece Bennett recently made the move from undergraduate student at Norfolk State University to graduate student at the University of California, Berkeley. Along with this change Franiece also applied for and was awarded the CIAN Diversity Fellowship. This award will assist her in completing her research and education goals. Below Franiece shares a bit more about herself and her research goals.

If you would like to learn more about applying for the Diversity Fellowship please contact CIAN Education.

Congratulations to Franiece Bennett
Recipient of the CIAN Diversity Fellowship

I am from Slidell, LA and I have a passion for creativity and love for art in any form or medium. My inclination to the sciences drew me to the field of engineering where I found creativity and practicality intertwined. As an undergraduate my junior year I was first introduced to CIAN based research when I worked with Dr. Demetris Geddis at Norfolk State University on a heterogeneously integrated long wavelength VCSEL-based transceiver circuit design for micro/nano scale device applications. Now as a first year graduate African-American female student, I wish to continue to promote the diversity of engineers and work towards realizing the functionality of future optoelectronic devices. By working in Dr. Chang-Hasnain’s research group at the University of California, Berkeley I am able conduct research related to silicon photonics and optical communications systems. As a CIAN Diversity Fellow I will be afforded the opportunity to conduct meaningful research that will benefit the center as well as further the influence of optoelectronic integration to conventional network systems.


My research project is one that will hybridize High Contrast Metastructure (HCM) applications with on-chip tunable Vertical Cavity Surface Emitting Lasers (VCSELs) to create an all-inclusive transmitter photonic integrated circuit. A micro-sized HCM is an ideal MUX due to its dimensions, which are smaller than the optical communication wavelength and an insertion loss of 0.5 dB. Tunable VCSELs are an appropriate optical output source due to their minimal thermal resistance at approximately 1.59 K/mW, low-cost fabrication processes, and continuous single mode tuning range at room temperature. From Finite-Difference Time-Domain simulation, multiplexing four on-chip channels into a single optical fiber will result in a coupling efficiency of up to 90% for 35nm 1dB bandwidth. To ensure proof-of-concept, the tunable VCSELs will have a characteristic continuous tuning range of at least ± 26 nm within the communication band. Also, the MUX can have no more than 21dB of loss, which is proportional to 90% coupling efficiency of multiple channels. The thermal resistance of the fabricated lasers will not exceed 1.6 K/mW.

Girls in Engineering Summer Camp at UC Berkeley

Led by female faculty members and graduate students, during the past summer UC Berkeley College of Engineering launched a summer camp designed to inspire middle school girls to explore careers in STEM fields (science, technology, engineering and math). The summer camp consisted of two separate periods in June and July respectively, one week for each, and hosted altogether about 60 middle schoolers from five East Bay schools. See our video here.

As a female graduate student from a male-dominated department (EECS), and a CIAN student specialized in the area of optoelectronics, I feel obligated and pleased to introduce the girls to see what can be fun and interesting about optics. Continue reading

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.
