Title: Micromechanical modulator
Inventor: GOOSSEN KEITH W
IPC: G02B26/00
Filed: 1994-11-30
Abstract: A method and apparatus for modulating an optical signal using a micromechanical modulator are disclosed.    The modulator comprises a membrane, which consists of at least one layer, and a substrate, spaced to form an air gap.  The layers of the membrane are characterized in that there is a relationship between the refractive indices of the layers and the refractive index of the substrate.  The membrane is suspended in a first position over the substrate by a flexible support arrangement.   Bias  is applied to  the membrane and the substrate to create an electrostatic force to move the membrane towards the substrate to a second position.   The reflectivity of the device to an optical signal changes as the membrane moves from the first position to the second position, thereby modulating the signal.
