高功率单高阶模倒置表面浮雕结构垂直腔面发射激光器
High power single-higher-mode VCSEL with inverted surface relief
摘要
Abstract
An inverted surface relief vertical-cavity surface-emitting laser(ISR-VCSEL)with annular light emitting window has been presented and investigated.The most prominent structural feature of the device is that the stable single-higher-order transverse mode emission is supported.The laser emits output power up to 9.8 mW at about six times threshold current with an SMSR close to 30 dB,and it can still keep the output power of 4 mW even at as high ambient temperature as 360 K.The measured far field power intensity shows a Gaussian-shaped beam profile with low divergence.关键词
