Fluoride microresonators for mid-IR applications
Ivan S. Grudinin, Kamjou Mansour, Nan Yu
We study crystalline fluoride microresonators for mid-infrared applications. Whispering gallery mode resonators were fabricated with BaF, CaF and MgF crystals. The qual…
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…
Frequency comb from a microresonator with engineered spectrum
Ivan S. Grudinin, Lukas Baumgartel, Nan Yu
We demonstrate that by varying the ratio between the linewidth and dispersion of a whispering gallery mode resonator we are able to control the number N of free spectral ranges sep…
Temperature measurement and stabilization in a birefringent whispering gallery resonator
D. V. Strekalov, R. J. Thompson, L. M. Baumgartel +2
Temperature measurement with nano-Kelvin resolution is demonstrated at room temperature, based on the thermal dependence of an optical crystal anisotropy in a high quality whisperi…
