Design of infrared and ultraviolet Raman lasers based on grating-coupled integrated diamond ring resonators

We investigate the opportunities of Raman lasers based on integrated single-crystal diamond ring resonators. We model continuous-wave (CW) Raman lasing action while taking into account the lasing directionality, the linear and nonlinear losses, and the coupling of the fields between the bus and ring sections of racetrack-shaped diamond ring resonators. Besides designing the ring resonators for a short-wavelength infrared (SWIR) and an ultraviolet (UV) Raman laser, we also design diamond gratings to couple light in and out of the resonators. Using our Raman lasing model, we determine the lasing directionality, pump threshold, and lasing efficiency of the considered SWIR and UV devices. We find that both can yield efficient CW operation with SWIR and UV lasing slope efficiencies of 33% and 65%, respectively. These results showcase the potential of integrated diamond ring Raman lasers for producing wavelengths that are challenging to generate with other types of integrated lasers.
