Abstract:
1. An effective mode index modifier that modifies light propagation in a waveguide, comprising: a Silicon-On-Insulator (SOI) wafer that includes an insulator layer and an upper silicon layer; a waveguide formed at least in part in the upper silicon layer of the SOI wafer, wherein the waveguide guides an optical signal by total internal reflection; at least one micro-electro-mechanical system (MEMS) having at least one movable component disposed a positive distance away from the waveguide; wherein application of voltage to the MEMS results in a variation of the distance between the at least one movable component and the waveguide, which in turn alters the effective mode index of the waveguide in a location proximate to the at least one movable component moveable object, thereby resulting in modification of light propagation in the waveguide.
