    摘要: A light emitting device including an array of light emitters to emit first light pulses. Each of the light emitters includes a saturable absorber and a waveguide having an electrically pumped gain region to emit the first light pulses. At least one reflector structure reflects the first light pulses into a nonlinear crystal by changing the direction of the first light pulses by an angle that is in a range of 70 to 110 degrees. The reflector structure includes a sub-wavelength grating structure to change the polarization of the first light pulses. A nonlinear crystal generates second light pulses such that the optical frequency of the second light pulses is two times the optical frequency of the first light pulses.

    摘要: A nonlinear crystal includes a plurality of poled zones implemented in a nonlinear material. The crystal has a first region and a second region. In the first region, the local average of a length of a period of the poled zones substantially increases with increasing distance from an origin. In the second region, the local average of the length of the period of the poled zones substantially decreases with increasing distance from the origin. The origin is located at an end of the crystal.

    摘要: 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.
