Performance Improvement of 2.0 μm GaSb Laser Diode by Facet Coating
摘要
基于InGaSb/AlGaAsSb材料体系, 制备出了一款高性能的镀膜激光器。为了性能对比, 同时制备了未镀膜激光器。未镀膜的器件在注入电流为3.0 A时, 室温连续模式下的输出功率达到300 mW, 最大插头效率为 8.3%。镀膜器件在注入电流为2.6 A时, 室温连续模式下的输出功率达到380 mW, 最大插头效率为15.6%; 另外, 在0.3~2.4 A的注入电流范围内, 镀膜器件的插头效率均大于10.0%, 激射波长均在2.0 μm附近。
Abstract
The coated laser with a high performance is fabricated based on the InGaSb/AlGaAsSb material system, and simultaneously the laser without facet coating is also fabricated for a performance comparison. The laser without facet coating working in the continuous-wave (CW) mode and under room temperature (RT) shows an output power of up to 300 mW at the injection current of 3.0 A and the maximum wall plug efficiency (WPE) is 8.3%. The laser with facet coating working in the CW mode and also under RT exhibits an output power of up to 380 mW at the injection current of 2.6 A and the maximum WPE is 15.6%. The WPE of the coated laser is always above 10.0% and the emission wavelength is around 2.0 μm at the injection current range of 0.3-2.4 A.
