摘要

本文提出了一种新的金属模式滤波垂直腔面发射激光器（MMF-VCSEL）的理论计算方法。使用了优化的P-DBR数量和金属层厚度。分析了金属模滤波结构对不同横模阈值增益的影响。与传统的氧化物限制VCSEL相比，MMF-VCSEL可以在8μm氧化物孔径下以基本横向模式工作。得益于大的氧化物孔径和小的金属孔径，有效地避免了电流拥挤效应，改善了VCSEL内部的热分布。

A novel metal-mode-filtered vertical-cavity surface-emitting laser with 8 μm oxide aperture and single mode output

In this study, a new theoretical calculation of metal-mode-filtered vertical-cavity surface-emitting laser (MMF-VCSEL) is proposed. The optimized number of P-DBR and the metal layer thickness are used. The effects of the metal mode filtered structure on the threshold gain of different transverse modes is analyzed. The MMF-VCSEL can operate in fundamental transverse mode under 8 μm oxide aperture compared with the conventional oxide-confined VCSEL. Benefit from the large oxide aperture and small metal aperture, the current crowding effect is effectively avoided and the heat distribution inside the VCSEL is improved.
