WAVEGUIDES AND DEVICES FOR ENHANCED THIRD ORDER NONLINEARITIES IN POLYMER-SILICON SYSTEMS

摘要

Systems and methods for manipulating light with high index contrast waveguides clad with substances having that exhibit large nonlinear electro-optic constants such as χ3. Waveguides fabricated on SOI wafers and clad with electro-optic polymers are described. Embodiments of waveguides having slots and input waveguide couplers are discussed. Waveguides having closed loop structures (such as rings and ovals) as well as linear or serpentine waveguides, are described. All-optical signal processing systems and methods for implementing devices such as variable delay lines, optical logic gates (for example an AND gate), optical multiplexers, optical self-oscillators, and optical clock generators are disclosed.
