ABSTRACT
We report an intra-cavity coherent combining of two distributed Bragg reflector (DBR) lasers with a combining efficiency of â¼84% on an InP generic foundry platform. The on-chip power of the intra-cavity combined DBR lasers is â¼9.5â
mW at the injection current of 42â
mA in both gain sections simultaneously. The combined DBR laser operates in a single-mode regime with a side-mode suppression ratio of 38â
dB. This monolithic approach paves the way toward high-power and compact lasers, which is useful in scaling integrated photonic technologies.
