Paper Abstract

In this paper we present an innovative tunable Fabry-Perot cavity micromachined in silicon. A short summary of the theoretical background of these filters is presented, followed by technical requirements for the design of the dielectric mirror composing the Fabry-Perot cavity and the cavity itself. Simulations and experimental data are demonstrated to be in good agreement. An in plane design is used to allow easy fiber alignment. The Fabry-Perot is tuned by an electrostatic comb drive actuator supported by a set of four springs to achieve a uniform modulation of the air gap of the filter. Only 15.4 V are required to tune the Fabry-Perot over 73nm bandwidth (covering more than the whole C-band) with a FWHM varying from 6 to 10nm. Transmission losses are -11dB.
