Abstract

Multijunction vertical-cavity surface-emitting lasers (VCSELs) have gained popularity in automotive LiDARs, yet achieving a divergence of less than 16° (D86) is difficult for conventional extended cavity designs due to multiple-longitudinal-mode lasing. Our innovation, the antireflective vertical-cavity surface-emitting laser (AR-VCSEL), addresses this challenge by introducing an antireflective light reservoir, where the electric field intensity is substantially higher than the gain region. This reduces the required cavity length for minimal divergence, preserving the single-longitudinal-mode lasing. A 6-junction AR-VCSEL array showcases a halved divergence and tripled brightness compared to its conventional counterpart. Various multijunction AR-VCSEL array designs achieve a divergence range of 8° to 16° (D86). Notably, a 7 μm AR-VCSEL emitter achieves 28.4 mW in single transverse mode lasing. AR-VCSEL stands out among semiconductor lasers, offering a well-balanced power density and brightness, making it a cost-effective solution for long-distance LiDARs. The antireflective cavity concept may inspire diverse applications in photonic devices beyond LiDARs.

摘要

多结垂直腔面发射激光器（VCSEL）在汽车激光雷达中越来越受欢迎，然而，由于多纵模激射，传统的扩展腔设计很难实现小于16°（D86）的发散角。我们的创新成果——抗反射垂直腔面发射激光器（AR-VCSEL），通过引入一个抗反射光储存器来应对这一挑战，在该储存器中电场强度远高于增益区。这减少了实现最小发散角所需的腔长，同时保持单纵模激射。与传统的6结VCSEL阵列相比，6结AR-VCSEL阵列的发散角减半，亮度提高了两倍。各种多结AR-VCSEL阵列设计实现了8°至16°（D86）的发散角范围。值得注意的是，一个7μm的AR-VCSEL发射器在单横模激射时可达到28.4 mW。AR-VCSEL在半导体激光器中脱颖而出，具有平衡的功率密度和亮度，使其成为长距离激光雷达的经济高效解决方案。抗反射腔概念可能会激发激光雷达以外的光子器件的各种应用。
