Low Threshold GalnAsP/InP Membrane BH-DFB Lasers
A single mode operation of 1.55 μm-wavelength GalnAsP/inP membrane BH-DFB laser was demonstrated under RT-CW optical pumping with a threshold power of 1.5 mW and a sub-mode suppression-ratio (SMSR) of 42 dB. We also demonstrated a membrane-based laser ...
