Abstract
Continuous wavelength tuning of 19.1 nm is reported for vertical-cavit y surface-emitting lasers. Stress-matched dielectric mirror stacks are added to the micromachined deformable-membrane top mirror to enhance reflectance, resulting in devices with 6.5% quantum efficiency and thr eshold current as low as 0.34 mA. The laser operates in single mode ne ar 968 nm with 24 dB mode suppression ratio and tuning voltages are be low 18 V. (C) 1997 American Institute of Physics.
