Abstract:
1. An analog optical modulator formed within an SOI structure including a silicon substrate, an overlying oxide layer and a relatively thin silicon surface waveguiding layer, the analog optical modulator comprising an optical interferometer formed within the relatively thin silicon surface waveguiding layer, the interferometer including an input optical waveguide, a pair of parallel waveguiding arms and an output optical waveguide, with an input Y-splitter disposed between the input optical waveguide and an input to the pair of parallel waveguiding arms and an output Y-combiner disposed between an output of the pair of parallel waveguiding arms and the output optical waveguide, a continuous wave (CW) optical input signal coupled into the input optical waveguide; and at least one silicon-insulator-silicon capacitance (SISCAP) optical waveguiding device disposed in at least one of said pair of parallel waveguiding arms, the SISCAP optical waveguiding device comprising
