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.
Claims4
An optical device comprising:
- a substrate;
- a device layer on the substrate;
- and
- a plurality of waveguide-based, electro-optic modulators connected in series by a waveguide structure in the device layer, each electro-optic modulator including an RF electrode, the plurality of electro-optic modulators including:
- a first electro-optic modulator and a second electro-optic modulator coupled in series by said waveguide structure, and a continuous integrated RF electrode integrated within the device layer and extending through the first electro-optic modulator and the second electro-optic modulator, a first length of the continuous integrated RF electrode being the RF electrode of the first electro-optic modulator, extending through the first electro-optic modulator, but not extending through the second electro-optic modulator and a second length of the continuous integrated RF electrode being the RF electrode of the second electro-optic modulator, extending through the second electro-optic modulator, but not extending through the first electro-optic modulator,
- wherein the plurality of electro-optic modulators and the waveguide structure are configured to receive light from at least one continuous wave light source, and generate a plurality of optical frequencies, said optical device comprising a frequency comb generator.
