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
