Tuning of the OEPO Outputs in Single-Mode and Multi-Mode Operation

Caption

a, b, Cavity-delay-independent frequency tuning in single-mode operation. By tuning the LO, the frequency of the single-mode oscillation is tuned. The cavity length is approximately 200 m, resulting in a 1-MHz FSR. The minimum tuning step in the experiment is 100 Hz, which is much less than the 1-MHz cavity FSR. c, d, Power spectra of the multimode operation with different spectral envelopes and frequency spacing of adjacent oscillation modes. The cavity parameters such as the cavity gain and pump frequency of the OEPO are tuned to achieve these multimode oscillation states
