Dispersion engineering and measurement in crystalline microresonators using a fiber ring etalon
Fig. 1. (a) Schematic of the experiment setup. Orange lines denote optical paths, and blue lines represent electric cables. A tapered fiber is employed to couple the laser in and out of the microresonator. The fiber cavity is put on a silicone rubber heater, and both of them are kept in a thermal insulation box. Temperature is set as 50°C in the experiment. FPC, fiber polarization controller; FG, function generator; PM, phase modulator; TC, temperature controller; FC, fiber cavity; PD, photodiode. (b) Transmission spectrum of the fiber cavity without phase modulation. The red dashed line is Lorentz fitting for the resonance, and the fitting shows that the loaded
