Numerical analysis of semiconductor lasers with FBG external cavity reflectors

摘要

Numerical simulations based on a multimode rate-equation model isused to study the ef- fect of fiber Bragg grating (FBG) externalcavity reflectors on the performance of multimode semicon- ductorlasers. The factors affecting the relative intensity noise and thewavelength stable range are dis- cussed. Design principles for theparameter selection of semiconductor lasers with FBG external cavityreflectors are given based on the numerical results.
