摘要：

We report a top-emitting micromechanical vertical-cavity surface-emitting laser (VCSEL) with a continuously tunable wavelength range of 31.6 mn, 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 1.2-4.5 mA while output power at 10-mA de 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.
