我们报道了一种顶部发射的微机械垂直腔面发射激光器（VCSEL），其连续可调谐波长范围为31.6 nm，是迄今为止VCSEL所展示的最宽的调谐范围。良好的激光特性保持在整个调谐范围内以935 nm为中心：连续波（CW）的阈值发生在1.24.5 mA之间，而输出功率在10 mA直流偏置保持在0.5和1.6 mW之间。通过分析作为发射波长的函数的脉冲微分量子效率，我们得出结论，悬臂梁设计的倾斜损耗不会显着影响调谐范围或激光器性能。
We report a top-emitting micromechanical vertical-cavity surface-emitting laser (VCSEL) with a continuously tunable wavelength range of 31.6 nm, the widest tuning range demonstrated by a VCSEL to date. Good laser characteristics are maintained throughout the tuning range centered at 935 nm: continuous-wave (CW) threshold occurs between 1.24.5 mA while output power at 10-mA DC bias remains between 0.5 and 1.6 mW. By analyzing the pulsed differential quantum efficiency as a function of emission wavelength, we conclude that tilt loss from the cantilever design does not significantly affect the tuning range or laser performance.
