摘要

控制氧化物约束垂直腔面发射激光器（VCSEL）中的横向模式是一个关键问题。我们展示了一种采用双异质结构高对比度光栅（HCG）作为顶镜来控制横向模式特性的 VCSEL。与采用均匀 HCG 的普通 HCG-VCSEL 相比，所提出的双异质结构 HCG-VCSEL 理论上可以抑制高阶横向模式。实验结果表明，与具有均匀 HCG 的普通 HCG-VCSEL 相比，双异质结构 HCG-VCSEL 的光谱宽度减小，基模红移，这与理论结果完全一致。据我们所知，这项工作提供了一种控制 VCSEL 横向模式的新方法。

Vertical-cavity surface-emitting laser with subwavelength photonic double heterostructures.

Control of transverse modes in the oxide-confined vertical-cavity surface-emitting laser (VCSEL) is a key issue. We demonstrate a VCSEL with a double heterostructure high-contrast grating (HCG) as the top mirror to control the transverse mode characteristics. Compared with the common HCG-VCSEL with a uniform HCG, theoretically the proposed double heterostructure HCG-VCSEL can suppress the higher-order transverse modes. Experimentally, the double heterostructure HCG-VCSEL has a reduced spectral width and red-shifted fundamental mode compared with a common HCG-VCSEL with a uniform HCG, which is consistent well with the theoretical results. This work provides a new, to the best of our knowledge, approach to control the transverse modes of the VCSEL.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
