Abstract

To overcome the serious current crowding effect in top-emitting vertical cavity surface emitting lasers (VCSELs) with large aperture, a distributed-ring-contact (DRC) VCSEL is proposed and demonstrated. A maximal cw light output power of more than 0.3 W and a wall-plug efficiency of 17.4% are achieved for a 300 μm-diameter VCSEL. The DRC VCSEL exhibits a more homogeneous emission profile, and the laser emits at 803.3 nm with a narrow spectrum (less than 0.2 nm FWHM).

摘要

为克服当前大孔径顶部发射垂直腔面发射激光器（VCSEL）中严重的载流子聚集效应，提出并演示了一种分布式环形接触（DRC）VCSEL。对于直径为300μm的VCSEL，实现了超过0.3W的最大连续波光输出功率和17.4%的壁插效率。DRC VCSEL表现出更均匀的发射分布，并且该激光器在803.3nm处发射，具有窄光谱（半高宽小于0.2nm）。
