HIGH-POWER SINGLE-MODE VERTICAL CAVITY-SURFACE EMITTING LASER

摘要

A vertical cavity-surface emitting laser (VCSEL) for emitting a single-mode laser including a multiple transverse mode VCSEL includes a top emitting region, and a dielectric film covering the top emitting region of the multiple transverse mode VCSEL completely, in order to limit the multiple transverse mode VCSEL to emit the single-mode laser.
