Tech Detective: Lasers at PARC
by Michael V. Copeland, Venture
Capital Journal, October 1, 2002
From the article:
"If there is one technology
in which the propeller heads at PARC are expert
it is lasers. Red ones, violet ones, blue ones,
invisible ones-they've got them all in their lab
on a beautiful hillside above downtown Palo Alto."
"Noble [Johnson] and the
PARC engineers specialize in semiconductor lasers,
which use layered crystals formed from material
like gallium nitride and gallium arsenide. Semiconductor
lasers have several advantages over their gas
counterparts: They use relatively little energy,
they are durable and, most importantly, they are
cheap. The development of inexpensive semiconductor
lasers emitting red or infrared light opened the
door to mass-market CD players, DVD players, laser
printers and a slew of other devices."
Copeland goes on to review PARC's
current work in vertical cavity surface emitting
lasers or VCSELs and ultra violet and blue lasers.
