Paper Abstract

The design and the fabrication of vertical InP-based micro- opto-electro-mechanical devices are reported. These are based on micromachined III-V semiconductor structures realized by selective removal of adapted sacrificial layers in order to produce Fabry-Perot resonant microcavity. Continuous wavelength running of 50nm around 1.55 micrometers for a 15 volt bias actuation has been demonstrated. Resonant peak full width at half maximum of about 10 nm at 1.5 micrometers has been performed on a InP/air gap multilayered interferometric filter. The integration of absorbing layers inside the cavity will allow us to realize resonant cavity enhanced photonic devices with thinner, and therefore faster, photodetector structures with high quantum efficiencies.
