Toxic Gas alarm testing today and tomorrow ....

SNF Lab Members and Allen Building Occupants:

Today and tomorrow the SNF staff in conjunction with an independent
testing company and Santa Clara county officials will be conducting
tests of each of the toxic gas detectors in our facility. Part of this
testing checks to make sure that appropriate blue toxic gas alarms and
fire alarms ring. As a result there will likely be at least a couple
.... and conceivably many ... times that the blue toxic gas alarms
and/or fire alarms may ring today and tomorrow.

We know that these are loud and hard to ignore. However, these, can be
safely ignored ... unless you quickly hear announcements that there is a
real emergency. Note: if there is a real smoke alarm, fire, earthquake,
or other emergency situation, the alarms will ring normally and the fire
department will be called, In that case it is important to make the SNF
staff aware of any real alarm situations such as a fire or medical
emergency.

While we apologize for the disruption that this testing causes, but this
is an important element of ensuring all of our safety in terms of proper
detection and notification of detected toxic gases during the entire year.

Thanks,

John

[Reminder] Special Seminar - Prof. Ivan Kaminow (UC Berkeley), Tuesday Dec.14, 4:15 PM, Nano 232



Special Seminar Presented by the Stanford Optical Society

Lightwave Modulators: Early Research at Bell Labs

Prof. Ivan P. Kaminow

EECS, UC Berkeley

 

Tuesday, December 14, 4:15 PM, Nano Center 232

Refreshments at 4PM

 

Ted Maiman's announcement of the ruby laser in May 1960 created great excitement worldwide, and particularly at Bell Labs. I was in the Microwave Systems Research Lab, soon to become the Lightwave Systems Research Lab, in Holmdel, NJ. Many of my colleagues decided to pursue laser research. Based on my experience with microwave systems, I decided to explore broadband light modulators that would be key for any telecom system. In my talk, I plan to touch on some of the highlights of a 15-year period of research on electrooptic modulators in the Bell Labs ambience. I include a 9 GHz travelling wave modulator, studies of electrooptic materials and photonic integrated circuits.

 

About the speaker

Ivan Kaminow retired from Bell Labs in 1996 after a 42-year career (1954-1996), mostly in lightwave research. At Bell Labs, he did seminal studies on electrooptic modulators and materials, Raman scattering in ferroelectrics, integrated optics (including titanium-diffused lithium niobate modulators), semiconductor lasers (including the DBR laser, ridge waveguide InGaAsP laser and multi-frequency laser), birefringent optical fibers, and WDM lightwave networks. Later, as Head of the Photonic Networks and Components Research Department, he led research on WDM components (including the erbium-doped fiber amplifier, waveguide grating router and the fiber Fabry-Perot resonator), and on WDM local and wide area networks. Earlier (1952-1954), he did research on microwave antenna arrays at Hughes Aircraft Company.

After retiring from Bell Labs, he served as IEEE Congressional Fellow on the staffs of the House Science Committee and the Congressional Research Service (Science Policy Research Division) in the Library of Congress. From 1997 to 1999, he returned to Lucent Bell Labs as a part-time Consultant. He also established Kaminow Lightwave Technology to provide consulting services to various technology companies, and to patent and litigation law firms. In 1999 he served as Senior Science Advisor to the Optical Society of America in Washington. He also served on a number of professional committees. He received degrees from Union College (BSEE), UCLA (MSE) and Harvard (AM, Ph.D.). He was a Hughes Fellow at UCLA and a Bell Labs Fellow at Harvard.

He has been Visiting Professor at Princeton, Berkeley, Columbia, the University of Tokyo, and Kwangju University (Korea). Currently, he is Adjunct Professor in EECS at University of California, Berkeley, where he has been teaching since 2004 (ee290F. Advanced Topics in Photonics [spring 2004]; ee233. Lightwave Systems [spring 2006]; seminar on Plasmonics [spring, fall 2007] and seminar on Photonics and Plasmonics [spring, fall 2008; spring, fall 2009; spring, fall 2010]).

He has published over 240 papers, received 47 patents, and has written or co-edited 5 books, the most recent being "Optical Fiber Telecommunications V A&B," co-edited with Tingye Li and Alan Willner, published in March 2008.

PhD Defense: Shen Ren, Monday, Dec 13, 2010

Stanford University PhD Oral Defense – Department of Electrical Engineering

 

Ph.D. Candidate: Shen Ren

Advisor: Prof. David. A. B. Miller

Date: Monday, Dec 13th, 2010

Time: 10am (Refreshments start at 9:45am)

Location: CISX Auditorium (101X)

Title: Ge/SiGe Quantum Well Waveguide Modulator for Optical Interconnect Systems

 

Abstract

Thanks to the development of silicon VLSI technology over the past several decades, we can now integrate far more transistors onto a single chip than ever before. However, this also imposes more stringent requirements, in terms of bandwidth, density, and power consumption, on the interconnect systems that link transistors. The interconnect system is currently one of the major hurdles for the further advancement of the electronic technology. Optical interconnect is considered a promising solution to overcome the interconnect bottleneck.

 

In this presentation, I will first briefly introduce the optical interconnect system. Then a special type of device in the optical interconnect system, the optical waveguide modulator that is based on Ge/SiGe quantum well (QW) structures, will be presented. Such QW structures can be grown monolithically on silicon substrates in a fully CMOS compatible fashion. For the first time, we demonstrated the selective epitaxial growth of these structures on patterned substrates. The selective epitaxy exhibits minimal pattern sensitivity under optimized growth conditions. Compared to its counterparts through bulk epitaxy, the p-i-n diodes from selective epitaxy demonstrate very low reverse leakage current and high reverse breakdown voltage. Strong quantum-confined Stark effect (QCSE) is, for the first time, demonstrated in this material system in the telecommunication C-band at room temperature. Then I will present our approach of integrating the Ge/SiGe QW active optical modulators into the silicon-on-insulator (SOI) waveguide platform through selective epitaxial growth. We proposed, analyzed, and experimentally demonstrated a novel approach to realize the butt coupling between SOI waveguide and Ge QW waveguide modulator using a thin dielectric spacer. 3.2dB modulation contrast ratio is achieved with merely 1V dynamic swing. We also show high speed modulation up to 3.5GHz, which is currently limited by our testing capability.

Asking for some information

Hello, labmembers,

This is Seongjae at Prof. Harris group.
If anyone has answers for questions below, please let me know.
Answers for multiple questions are much better of course
but even if you have an answer for one question, that will be fine too.

The intend is to use Cr as the hard mask to etch multiple layers
and remove it by CR-14 minimizing the exposure of the lower layers
to CR-14 since the layers in my concern turned out to be also etched
by CR-14 significantly by SEM inspection.

1. Cr etch rate in drytek 4 at a usual oxide etch recipe.

2. Cr etch rate in pquest at a usual GaAs etch recipe.

3. Cr etch rate by CR-14 (wet etchant for Cr) as accurately as possible.

Thank you for your help in advance.

- Sincerely, Seongjae.

Problem p5000etch SNF 2010-12-09 22:48:18: Chamber C offline

I accidentally put the Poly Etch recipe in B slot and selected C ONLY, so wafer was just sitting in the elevator in there. I put poly etch into slot C and hit RUN and nothing happened, and then realized it was in Manual mode, so I changed that to automatic and hit RUN, and it turned green, but it didn't seem like anything was happening, so I hit STOP (was it during pumpdown?), and recovered my wafer using the instructions. But now chamber C cannot do further processing. Sad.

Reminder: Allen Building Holiday Party is Today!!!

The annual Allen/X Building holiday party is in just one hour!

Please come to the annual Allen Building holiday party. This will be
