Abstract
A GaAlAs/GaAs micromachined thermally tunable vertical cavity filter with a low tuning voltage is proposed and its fabrication described. The integration of a thermal strain control layer and heating element enables wavelength tuning induced by heating. Wavelength tuning of 23.2 nm with a low tuning voltage of 4.7 V is demonstrated experimentally
