Advances on nonlinear phenomena in Whispering-Gallery Mode resonators
Résumé
In this communication, present some of our latest results related to Kerr optical frequency comb generation. We investigate the conditions under which the energy conversion from the lightwave to the microwave spectral ranges is optimized. Our main finding is that the optimal regime features a pump-to-sidemode ratio smaller than 4 dB, corresponding to a conversion efficiency better than 40 %.
