Abstract: An optical modulator includes optical material(s) and first and second differential electrode pairs. The optical material(s) exhibit an electro-optic effect and include lithium. The optical material(s) include first and second waveguides and first and second slab portions adjoining the first and second waveguides. The first differential electrode pair has electrodes arranged on opposing sides of the first waveguide. The second differential electrode pair has electrodes arranged on opposing sides of the second waveguide. The negative electrodes are arranged on distal sides of the waveguide relative to the other waveguide. The positive electrodes are arranged on proximal sides of waveguide relative to the other waveguide. The first and second waveguides, the first and second slab portions, and the first and second differential electrode pairs reside on a substrate structure. No portion of the first slab portion is between the first or second differential electrode pair and the substrate structure.

Abstract: An integrated electro-optic frequency comb generator based on ultralow loss integrated, e.g. thin-film lithium niobate, platform, which enables low power consumption comb generation spanning over a wider range of optical frequencies. The comb generator includes an intensity modulator, and at least one phase modulator, which provides a powerful technique to generate a broad high power comb, without using an optical resonator. A compact integrated electro-optic modulator based frequency comb generator, provides the benefits of integrated, e.g. lithium niobate, platform including low waveguide loss, high electro-optic modulation efficiency, small bending radius and flexible microwave design.

Abstract: An optical device including a plurality of electrodes, an electro-optic component, an optical grating, and a buried back reflector is described. The electro-optic component includes at least one optical material exhibiting an electro-optic effect. The optical grating is optically coupled with the electro-optic component. In some embodiments, the optical grating includes a vertical optical grating coupler. The buried back reflector is optically coupled with the optical grating. The buried back reflector is configured to increase a coupling efficiency of the optical grating to an out-of-plane optical mode and configured to reduce a performance perturbation to the plurality of electrodes. The buried back reflector may include a metal layer having a thickness of at least thirty nanometers and not more than five hundred nanometers.
