摘要

本文对峰值发射波长为637 nm的algainp基红色激光二极管的光学特性进行了数值分析。对两种基于algainp的红色激光二极管进行了比较研究，即一种没有AlGaP/GaP超晶格，另一种有三对AlGaP/GaP超晶格。结果表明，在输出功率、受激复合率和光增益方面有了明显的提高。优化后的结构显著增强了空穴注入，导致光学增益大幅增加，激光阈值从670 a /cm2降低到545 a /cm2。此外，AlGaP/GaP超晶格设计的斜率效率从0.2 W/A提高到0.4 W/A。与没有超晶格的器件相比，AlGaP/GaP超晶格的掺入显著提高了AlGaInP基红色激光二极管的整体性能。

Leveraging algap/gap superlattices to elevate AlGaInP red laser diode performance

This study presents a numerical analysis of the optical characteristics of an AlGaInP-based red laser diodes with a peak emission wavelength of 637 nm. Two AlGaInP-based red laser diodes i.e., one without and one with three pairs of AlGaP/GaP superlattices into the active region are comparatively studied. Results show a marked improvement in the output power, stimulated recombination rate, and optical gain. The optimized structure significantly enhances hole injection, leading to a substantial increase in optical gain and a reduction in the lasing threshold from 670 A/cm² to 545 A/cm². Additionally, the slope efficiency of the AlGaP/GaP superlattices design is increased from 0.2 W/A to 0.4 W/A. The incorporation of AlGaP/GaP superlattices has been shown to significantly enhance the overall performance of AlGaInP‑based red laser diodes compared with the device without superlattices.
