Impact of cavity spectrum on span in microresonator frequency combs
Ivan S. Grudinin, Lukas Baumgartel, Nan Yu
We experimentally study the factors that limit the span in frequency combs derived from the crystalline whispering gallery mode resonators. We observe that cavity dispersion is the…
Polarization conversion loss in birefringent crystalline resonators
Ivan S. Grudinin, Guoping Lin, Nan Yu
Whispering gallery modes in birefringent crystalline resonators are investigated. We experimentally investigate the XY--cut resonators made with LiNbO, LiTaO and BBO and ob…
Broadband second harmonic generation in whispering gallery mode resonators
Guoping Lin, Josef U. Fürst, Dmitry V. Strekalov +1
Optical frequency conversion processes in nonlinear materials are limited in wavelength by the accessible phase matching and the required high pump powers. In this letter, we repor…
