Abstract :
A novel optical design is provided for developing tunable, active microoptoelectromechanical system (MOEMS) devices. The active layer is placed outside and on the top of an asymmetric Fabry-Perot resonant cavity and the selectivity is obtained by controlling the relative phase of the incident and reflected waves, a mechanism which we call the phase-matching and pseudoresonance-enhancement (PMPRE). We propose a practical design for a tunable MOEMS photodetector based on this PMPRE principle.
