I recently successfully defended my PhD dissertation, so I'm all done
except for getting the final paperwork submitted.
I'd like to thank the members of the sci.optics community for the help
they've given me with various optics-related questions during the
process. I'd especially like to thank Phil Hobbs and Tony Siegman for
their assistance.

Glad to have helped, even if only in small ways, and congratulations!

P.S. -- About 55 years ago, Ted Maiman finished his PhD thesis in the
Physics Dept here, working with Willis Lamb., then took a year-long trip
around the world. Then he came back to California, got a job, and
(ignoring the objections of his boss) invented the laser. Is that a
role model, or not? |

Congratulations! Now you get to help the newbies. ;)

One role model I wish I could have followed is Richard Feynman.

"CMOS-Compatible On-Chip Optical Interconnects"
Basically, we're trying to replace routing signals on microprocessors
and other integrated circuit in metal with a nanoscale fiber optic
network. The unique thing about our approach is that we're doing this
solely with materials that exist in any standard CMOS process. (With
the caveat that we're using an off-chip laser source.) The material
(and therefore equipment) compatibility substantially reduces barriers
to adoption. Given that modern IC fabs cost a significant fraction of
the GDP of a small country, the people who own and run fabs are
understandably somewhat risk adverse.
Bottom-line, the overall system performance needs to be 5x to 10x faster
to be compatible with leading-edge processes, but we think we know how
to do this. Given that we were fabricating our samples in a
trailing-edge process (it was cheap...), we're encouraged by the results
we got. We've even demonstrated practicality of the idea in a
full-blown IC chip. Didn't run as fast as we wanted, but that was due
to underestimation of circuit parasitics.

I certainly kept track of him, but my attempts to imitate him were
futile.

What a surprise! Congress needs to pass one of those Soviet style laws
to outlaw the parasites.

Indeed, but these were the days where students were not burdened with
loans and debts (and HR investigations concerning your credit report,
your youthful internet indiscretions and the like) and could indulge in
such mind enriching pursuits.
As to "ignoring the objections of his boss", said boss is now under such
pressure from his/her own management to produce tangible "bottom line"
results that tolerating insubordination is out of the question, even as here
"creative insubordination". :-(
Congrats to Bob!

Worse this "creative insubordination" would be construed as "playing in your
own sandbox and acting non-synergistically" with respect to the other
members of your group thus branding you a "non-team player", fodder for the
next round of ritual and obligatory "keep'em on their toes" layoffs. |

It is common for free spirits such as Ted Maiman to disparage other free
spirits once they become bosses themselves. That is being human. I know
as fact that Maiman disparaged this kind of insubordination once he
became president of Korad.
