Hybrid all optical silica waveguide modulator using non-linear electro-optic components

摘要

Generally, the present invention is an optically controlled optical waveguide circuit comprising a substrate 30, an inorganic waveguide core 34 disposed within one or more cladding layers 36 upon the substrate 30 and an active cladding drop-in component 40 comprising a non-linear optical material adjacent to the waveguide core wherein the phase of an optical signal within the waveguide core may be modulated by controlling the index of refraction of the active cladding region. An embodiment of the present invention uses an inorganic optical waveguide 34 with a drop-in component of non-linear silica 40 as an active cladding to provide a phase modulator for a Mach-Zender interferometer which can be used to implement high speed low loss switching of optical signals.
