摘要: A light emitting device including a waveguide having an electrically pumped gain region, a saturable absorber, a nonlinear crystal, an inclined mirror, and a light-concentrating structure. Light pulses emitted from the gain region are reflected by the inclined mirror and focused by the light-concentrating structure into the nonlinear crystal in order to generate frequency-converted light pulses. The gain region, the saturable absorber, the light-concentrating structure and the inclined mirror are implemented on or in a common substrate. The resulting structure is stable and compact, and allows on-wafer testing of produced emitters. The folded structure allows easy alignment of the nonlinear crystal.

摘要: A light emitting device comprises a waveguide having an electrically pumped gain region, a nonlinear medium, and an inclined mirror. Light pulses emitted from the gain region are reflected by the inclined mirror into the nonlinear medium in order to generate frequency-doubled light pulses. The gain region and the inclined mirror are implemented on the same substrate. The resulting structure is stable and compact, and allows on-wafer testing of produced emitters. The folded structure allows easy alignment of the nonlinear crystal.

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.
