Abstract

We report on successful fabricating of GaSb-based type-I quantum well distributed Bragg reflector (DBR) lasers emitting at 2080nm. Second-order Bragg gratings of chromium were patterned by electron beam lithography. For 1.5- mm-long laser diode, single mode continuous-wave operation with side mode suppression ratio (SMSR) as high as 30dB is obtained. The line-width of the lasing wave is kept as narrow as 70MHz. The devices show a stable single mode operation with current tuning rate of 0.01nm/mA.
