MONOLITHICALLY INTEGRATED DISTRIBUTED BRAGG REFLECTOR LASER

摘要

ABSTRACTSEMICONDUCTOR LASERA semiconductor laser has distributed Braggreflectors (11,13) in the form of waveguides eachconsisting of a core layer (22,24) of polyimide orsilicon nitride and cladding layers (21,23,25) orSiOx (x-2). The waveguides are monolithically integratedwith the active medium (12). Alternatively the lasermay have one distributed Bragg reflector and oneordinary mirror. With the dielectric materials used inthe waveguides optical losses are reduced andtemperature stability improved compared with knowndistributed Bragg reflector lasers with semiconductorwaveguides.
