Abstract

We have fabricated MBE grown, selectively oxidized multi-mode GaAs QW VCSELs with 730 /spl mu/A threshold, 8.5 mW output power and 40.3% conversion efficiency. Single-mode devices show 1.2 mW output power and better than 30 dB side mode suppression.
高效选择性氧化砷化镓(/spl λ /=830 nm)垂直腔激光器
我们制备了MBE生长的选择性氧化多模GaAs QW VCSELs,其阈值为730 /spl mu/A,输出功率为8.5 mW,转换效率为40.3%。单模器件的输出功率为1.2 mW,侧模抑制优于30 dB。
