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.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
