ABSTRACT:
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.
