Monolithically-integrated wavelength-selective receivers are needed for dense wavelength-division multiplex transmission in the 1.55 micrometers wavelength regime. We present a novel concept for tunable optical Fabry-Perot filters with long resonant cavities of about 30 micrometers . III-V semiconductor technology compatible to PIN detector integration is applied to fabricate bulk-micromachined movable membrane Bragg mirrors. The initial membrane curvature as well as the actuation-induced bending are analyzed using a white light interferometer. Continuous filter tuning achieved by thermal or electrostatical actuation is analyzed in the optical as well as in the mechanical regime. Opto-mechanical constraints of the realized filters are discussed in view of novel epitaxial demands and optimum design for micro-opto- electro-mechanical receiver systems.
