Abstract
A light source including a light emitting unit, a nonlinear medium, and a resonant grating. The light emitting unit is arranged to emit a first light into the nonlinear medium. The nonlinear medium is arranged to generate a second light such that an optical frequency of the second light is higher than an optical frequency of the first light. The resonant grating is arranged to stabilize an optical frequency of the first light by providing optical feedback to the light emitting unit.
Claims19
A light source, comprising:
- a light emitting unit;
- a nonlinear medium;
- and
- a resonant grating,
- wherein said light emitting unit is arranged to emit a first light into said nonlinear medium, said nonlinear medium is arranged to generate a second light such that an optical frequency of said second light is higher than an optical frequency of said first light, wherein the resonant grating is arranged to stabilize the optical frequency of said first light by providing an optical feedback to said light emitting unit, and wherein the resonant grating is arranged to provide said optical feedback based on an excitation of a leaky waveguide mode in a waveguide of the resonant grating.
A method for generating light by using a light source comprising a light emitting unit, a nonlinear medium, and a resonant grating, said method comprising:
- emitting a first light from said light emitting unit into said nonlinear medium;
- generating a second light in said nonlinear medium such that an optical frequency of said second light is higher than an optical frequency of said first light;
- and
- providing optical feedback to said light emitting unit by said resonant grating so as to stabilize the optical frequency of said first light,
- wherein said optical feedback is provided based on excitation of a leaky waveguide mode in a waveguide of the resonant grating.
