my work life: part A1

The computer photos were too boring? I appologize that strict company rules restricted me from posting much of the stuff and data I have been working on.

Let me try to spice it up with allowed photos:

1) How about this one, courtesy of U.S.Army stock photos (free copyright)?

2) How about these: a very small part of the data that was approved for public disclosure in scientific journals.

my work life: part A

Continue studying lasers and photonics wonders, but with "the 20th centry wonder tool":

Graduation

After five years, I got to try the dress.
*Thanks to Roshi's husband who shot this photo.

My PhD life: part D

Believe it or not, these electrical engineering and physics experimental data acturally form pretty artistic graphs:

My PhD life: part C

Laser characterization system, on a "bread-board" table (another cooking term!)

The photo appears to be chaotic, because it was taken with room lights on. Once the room light is switched off, and all dust covers are removed, there will be dozen’s of perfectly aligned infrared laser beams running across the table, with pin-point accuracy (better than 10-nanometer precision).

For people likes complete darkness, complete silence, and complete control, the laser characterization is a moment of Zen. I still vividly remember the moment my first laser line jumping up on the OSA (optical spectrum analyzer) screen.

*Photo courtesy of Mr. Ling Lu.

My PhD life: part B2

Did I forget to mention our high resolution cookie inspector (a.k.a. field emission scanning electron microscope, Hitachi S-4800)?

my PhD life, part B

Of course, a kitchen needs more than cooking pots.

Here are cookie patterning machines (e-beam lithography, and optical aligners), baking ovens, water tabs (a.k.a wet benches) ....

And, may other kitchen utilities, with too many photos to show one by one here.

My PhD life, part A

This yellowish "cleanroom" was the place-to-go for years to me. For people not in semiconductor business, a cleanroom can be better described as a super-clean kitchen.
Kitchen, yes, I'm not joking.
I have photos to prove it. And thanks go to Mr. Ling Lu for shooting the photos for me.
This is the staging room, for changing from regular clothes into cover-all jumpsuits. This is cooking pot #1 (a.k.a. an electron beam evaporator for dielectric coating)
Cooking pot #2 (a.k.a. metal evaporator)
cooking pot#3 (a.k.a ECR, electron cyclotron resonance)
cooking pot #4 (a.k.a. ICP, Inductive coupled plasma)
