Abstract :
Monolithic, C- and L-Band, digital supermode distributed Bragg reflector (DS-DBR) lasers are presented with equivalent process and performance. Laser pairs can cover over 200 consecutive 50 GHz channels with side mode suppression ratio (SMSR) >45 dB and ex-facet power levelled at 16.5 dBm.
