Title: Fabry-Perot optical switch

Abstract: The absorption of a spacer material in a Fabry-Perot type structure is changed to achieve an optical switching function. In one embodiment, the spacer material is a semiconductor material and an electronic control signal changes the Fabry-Perot between a transmissive state and a reflective state. In the reflective state, the device operates as a switch can be modeled as a mirror on a substrate of quasi-infinite thickness. In a further embodiment, a wavelength-selective optical component is placed between the input of the switch and the Fabry-Perot structure to improve the spectral response of the switch.
