ELECTRO-OPTICAL MODULATOR USING WAVEGUIDES WITH OVERLAPPING RIDGES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18526985 titled 'ELECTRO-OPTICAL MODULATOR USING WAVEGUIDES WITH OVERLAPPING RIDGES
Simplified Explanation
An optical modulator described in the patent application includes a lower waveguide, an upper waveguide, and a dielectric layer between them. When a voltage potential is applied between the waveguides, they form a silicon-insulator-silicon capacitor (SISCAP) guide for efficient optical modulation of a signal passing through.

Original Abstract Submitted
An optical modulator may include a lower waveguide, an upper waveguide, and a dielectric layer disposed therebetween. When a voltage potential is created between the lower and upper waveguides, these layers form a silicon-insulator-silicon capacitor (also referred to as SISCAP) guide that provides efficient, high-speed optical modulation of an optical signal passing through the modulator. In one embodiment, at least one of the waveguides includes a respective ridge portion aligned at a charge modulation region which may aid in confining the optical mode laterally (e.g., in the width direction) in the optical modulator. In another embodiment, ridge portions may be formed on both the lower and the upper waveguides. These ridge portions may be aligned in a vertical direction (e.g., a thickness direction) so that ridges overlap which may further improve optical efficiency by centering an optical mode in the charge modulation region.
