Abstract :
A 1.5 mu m-wavelength dynamic-single-mode laser with high-low reflection grating structure aiming at high output and uni-directional output operation has been obtained for the first time using a selective etching process and low-pressure MOVPE regrowth. A front/rear output power ratio exceeding 50 and side-mode suppression ratio (SMSR) greater than 39 dB were obtained at 1.3 times the threshold.
