US 2026/0189304 A1 · APPARATUS FOR GENERATING OPTICAL PULSE UTILIZING OPTICAL WAVEGUIDE DISPERSION AND METHOD THEREOF

Abstract

An optical pulse generating apparatus utilizing optical waveguide dispersion and a method thereof are disclosed. This apparatus includes a sine wave generator generating one of a plurality of sine waves and a phase modulator modulating incident light from a laser using the sine wave generated by the sine wave generator. This apparatus further includes a phase controller that controls the sine wave generator to generate one sine wave by transmitting sine wave information used in generation of an optical pulse selected by a user, and controls an optical waveguide connected to a phase modulator by transmitting optical waveguide information used in generation of the optical pulse to the optical waveguide connector. The sine wave information includes frequency information and amplitude information (or modulation index information) for generation of an optical pulse, and the optical waveguide information includes length information (or dispersion value information) for generation of an optical pulse.
