David Vandervoet graduated as an electrical engineering major in 1967 and was part of the first class ever to go through UCSB College of Engineering from freshman to senior year.

After graduating, Vandervoet began his career designing and launching major US satellites. He took some time to share his stories about the College in its early years, reflecting on the great community, protests, pranks, and how things have evolved in the last 50 years.

How many students were in the College of Engineering at the time and what was the community like?
Not sure but I would guess maybe 80-100. I was the first class to go through engineering from freshman to senior. Maybe there were 30 freshmen in my class.

What was student life at the College like in the 1960’s?
It started in the Arts Building and classes were small. We knew our professors very well. There were also a lot of protests, mostly by non-students in Isla Vista, and multiple police actions with protestors stopping us from getting to class.

What are some of the best memories you had while as a student?
Getting up the courage as a freshman to go into Dean Conrad’s office in the Arts building and meet him. I figured that I was paying part of his salary and he should know who I was. The meeting went very well. He was gruff but said he wished more students would come see him.

Dean C later invited me to his house to show me how he made violins. He imported very special wood from somewhere in Europe. He dried the wood for two years in some drying equipment that he made. He had very fine hand tools to do custom work in the violins. But what impressed me the most was that he would use an oscilloscope to tune them. He was still an engineer at heart.

Who was/were your mentor(s) as a student and how did they affect your life?
Dr. Heidbreder and Dr. Mattai. I learned theoretical communication theory from Dr. Heidbreder that got me started in the satellite business.

Is there something that happened when you went to COE that current students would have a hard time believing?
I climbed the outside bricks to the 5th floor on the end of the engineering building and taped a large sign that said “Welcome to Earl Hall” (our lab technician). Earl was a survivor of Pearl Harbor bombing and lived because he went to sleep Saturday night with his shoes on and could run across the burning deck of his ship on December 7 and dive into the water because of his shoes. He still wore his shoes to bed in the 1960s. Dean Conrad was annoyed but no one was brave enough to climb the bricks and take it down.

Photonics Spectra magazine Q&A with ECE Professor John Bowers

January 6th, 2017

cover of jan 2017 issue of photonics spectra
“The Revolution Has Just Begun Q&A with John Bowers” — Photonics Spectra speaks with Bowers about The American Institute for Manufacturing Integrated Photonics (AIM), his breakthrough work and the impact of integrated photonics on medicine, communications and defense.

One of the foremost names in the world of integrated photonics is John Bowers, Ph.D., who is credited with leading a team that successfully demonstrated an electrically pumped hybrid silicon laser a decade ago. That advance has paved the way for the commercial production of high-bandwidth silicon photonic devices. Today, Bowers is leading UC Santa Barbara’s Institute for Energy Efficiency’s involvement in the AIM initiative and is a central figure in this exciting field.

Q: Could you provide us with a snapshot of where you see the state of integrated photonics at the moment?
A: Integrated photonics is transforming telecommunications and data communications. Infinera, Acacia and others are introducing new telecommunication products with much higher capacity and performance that have been enabled by integration. Intel, Luxtera, Lumentum, Finisar and others are increasing capacity and lowering cost by integration. Virtually all 100-Gbps transceivers are highly integrated, and the next generation at 400 Gbps are only possible with integration. This started with integration on InP but high volumes are now being shipped by many silicon photonics suppliers, including Intel, Luxtera, Acacia and others.

Additional Questions (see full article):

  • Please elaborate on how you feel integrated photonic circuits are likely to impact such fields as transportation, medicine and defense in the years ahead?
  • Your work in ’06/’07 successfully bonding III-V material to a silicon waveguide has been cited as one of the seminal breakthroughs in integrated photonics. A decade later, can you share your reflections on this work and some of the primary challenges you overcame?
  • Has the hybrid silicon III-V laser reached commercial viability?
  • In 2015, the AIM initiative was formed and you were tasked with heading up UC Santa Barbara’s Institute for Energy Efficiency’s involvement in the program. Can you discuss recent advances?
  • How is integrated photonics likely to transform the world in which we live in the years and decades ahead?

Photonics Spectra is today’s leading source of technological solutions and of news and information about photonics. It is the magazine referred to worldwide by the largest audience of photonics engineers, scientists and end users. Integrating all segments of photonics, Photonics Spectra is unique in that it provides both technical and practical information for every aspect of the global industry.

John E. Bowers holds the Fred Kavli Chair in Nanotechnology, and is the Director of the Institute for Energy Efficiency. He is a member of the National Academy of Engineering, National Academy of Inventors, a fellow of the IEEE, OSA and the American Physical Society, and a recipient of the IEEE Photonics Award, OSA Tyndall Award, OSA Holonyak Prize, and the IEEE LEOS William Streifer Award.

The National Academy of Engineering has named UCSB Chancellor Henry T. Yang the recipient of the 2016 Arthur M. Bueche Award. The award, which consists of a commemorative medal, was presented at the academy’s annual meeting earlier this month in Washington, D.C.

Established in 1982, the award honors an engineer who has shown dedication in science and technology, as well as involvement in determining United States science and technology policy, promoting technological involvement and contributing to the enhancement of the relationship among industries, government and universities.

Yang, also a professor in UCSB’s Department of Mechanical Engineering, was cited for “seminal research in aerospace, civil, and mechanical engineering; superb contributions to national science and technology policy; and enhancements to international technological development and cooperation.”

“The Arthur M. Bueche Award is one of the three awards presented annually to outstanding engineers by the National Academy of Engineering, which is the premier institution of U.S. engineers in all fields,” said Rod Alferness, dean of UCSB’s College of Engineering.

ECE Prof. Yuan Xie and graduate student’s paper recognized as an IEEE Micro “Top Picks from the 2015 Computer Architecture Conferences”

October 31st, 2016

cover of ieee micro vol. 36, issue 3
With one of the most significant computer architecture papers of 2015, ECE faculty Yuan Xie and graduate student Shuangchen Li are recognized by the Institute of Electrical and Electronics Engineers (IEEE) Micro’s Top Picks

Their paper titled “Architecture Exploration for Ambient Energy Harvesting Nonvolatile Processors,” which was originally published in 21nd IEEE Symposium on High Performance Computer Architecture (HPCA 2015) and won the best paper award, was chosen by IEEE’s Micro magazine for its 2016 issue on “Micro’s Top Picks from the Computer Architecture Conferences”, and published as “Nonvolatile Processor Architectures: Efficient, Reliable Progress with Unstable Power ” in IEEE MICRO Vol.36, Issue 3.

The paper explores the design space for a nonvolatile processor across different architectures, input power sources, and policies for maximizing forward progress in a framework calibrated using measured results from a fabricated nonvolatile processor. The UCSB team, together with collaborators from Penn State and Tsinghua University, proposes a heterogeneous microarchitecture solution that efficiently capitalizes on ephemeral power surpluses.

IEEE Micro magazine publishes its yearly “Micro’s Top Picks from the Computer Architecture Conferences”, which collects the previous year’s most significant research papers in computer architecture based on novelty and potential for long-term impact. Any computer architecture paper (not a combination of papers) published in the top conferences of prior year is eligible. The Top Picks committee recognizes those significant and insightful papers that have the potential to influence the work of computer architects for years to come. Li and Xie’s paper is one of the 11 final winners out of hundreds of candidates selected by the committee.
