Short-cavity DBR laser using vertical groove gratings for large-scale photonic integrated circuits

Abstract We present a novel compact distributed Bragg reflector (DBR) laser using InP-InGaAsP deep ridge waveguides with vertical groove gratings. Stable single-mode laser operation was achieved with an active cavity length down to 25 mum and a threshold current of 14 mA. The devices are promising building blocks in large-scale photonic integrated circuits because of their simple structure and low power consumption
