Abstract
By a maskless PBH (planar buried heterostructure) LPE regrowth technique, we improved the hetero-interface of GaInAsP/InP circular BH structure. In this report, we demonstrate a low threshold 1.3 μm BH type surface emitting laser using this technique. We call this type of device circular PBH surface emitting laser (CPBH-SELD).
