Bandwidth10 was founded in February 2011 to market its tunable, singlemode, 1550 nm long-wavelength VCSELs and transceivers for datacom applications. 


Bandwidth10’s innovative  High-Contrast Grating (HCG) VCSEL technology was developed by the founders while at the University of California, Berkeley.  Dr. Chase, Dr. Rao and Dr. Huang completed their Ph.D. thesis research on VCSELs with a completely new concept for a top mirror, a High-Contrast Grating (HCG).  The HCG (seen below) is a single layer, ultra-thin grating made of a high index material with a sub-wavelength period, which exhibits a much broader reflection band than conventional Distributed Bragg Reflectors (DBR).

Using the HCG as a tunable mirror, as shown below, leads to a wafer-scale, low cost fabrication process for BW10’s long-wavelength 1550-nm, singlemode VCSEL transceivers.
