Abstract :
We have proposed a novel micromachined vertical cavity tunable filter with a thermal strain control layer, which enables wavelength tuning induced by heating. We show the possibility of a large tuning range of over 100 nm. Experimentally, we demonstrate both negative and positive wavelength tuning for micromachined GaAlAs/GaAs filters.
