RE: news item -- longwave VCSELs
Thanks for the info!
FYI, at the March 2000 Plenary in Albuquerque, Picolight presented results
from longwave VCSELs which also used a one-step epitaxial growth and direct
electrical pumping. The presentation is posted on the website. Although
the wavelength was shorter, 1170nm, the single-mode device operated CW past
90C temperatures, showed no sign of degradation after 2000 hours of rel test
at 70C, and transmitted a 3Gb/s eye over 10km of fiber. I am confident
these and better performances will be achieved at 1310nm.
Yes, LongWave VCSELs are happening!

Subject: news item -- longwave VCSELs
significantly important issue for 10GbE development, from Photonics Online:
1) Direct electrical pumping powers 1.3 mm VCSEL TECHNICAL NEWS:
One-step growth process and direct electrical pumping open the doors to
the telecom market for a 1.3 mm vertical cavity surface-emitting laser.
Potentially more manufacturable and economical than Gore's 1.3 um VCSEL that
optically pumped by an electrically-pumped 850-nm VCSEL wafer-bonded to the
device, the Sandia VCSEL has the potentially to significantly affect datacom
allowing it to leverage technology developed for long haul networks. Yvonne
