摘要 | A short-cavity semiconductor laser heterostructure, such as a vertical-cavity surface emitting laser (VCSEL) comprising a laser cavity having upper and lower surfaces and an active region disposed between the upper and lower surfaces for generating light and emitting light substantially perpendicular to the upper surface of the cavity, an upper high contrast grating (HGC) mirror disposed adjacent to the upper surface of the laser cavity, and a lower HCG mirror disposed adjacent to the lower surface of the laser cavity. |
