Gallium Arsenide based photonic crystal surface emitting lasers
Photonic crystal surface emitting lasers (PCSELs) are an emerging class of semiconductor laser which incorporate a 2D photonic crystal into a semiconductor laser structure to provide large area 2D feedback and surface emission. These devices have a number of desirable properties, chief of which is …
