OPTICAL FREQUENCY COMB LIGHT SOURCE AND METHOD FOR GENERATING OPTICAL FREQUENCY COMB

摘要

This application discloses an optical frequency comb light source and an optical frequency comb generation method. The light source includes a laser diode, a coupler, a Kerr nonlinear device, a beam splitter, and a phase shifter. The laser diode is connected to one input port of the coupler, and the other input port of the coupler is connected to an output port of the phase shifter. An output port of the coupler is connected to an input port of the Kerr nonlinear device. An output port of the Kerr nonlinear device is connected to an input port of the beam splitter. One output port of the beam splitter is connected to an input port of the phase shifter. The other output port of the beam splitter is configured to output a plurality of optical frequency combs. By using the apparatus, a multi-wavelength light source with relatively high power may be provided, and a related requirement for output power of the multi-wavelength light source in actual network deployment may be met.
