Abstract

A versatile angled fiber coupling platform for magnesium fluoride whispering gallery mode resonators is used to investigate nonlinear frequency conversion across 1.5 and 2 μm bands. We characterize MgF₂ microcavities of varying sizes (4.3 mm, 1.9 mm, and 0.73 mm in diameter), achieving quality factors up to 2×10⁹ at 1.55μm and 5×10⁸ at 1.94μm. In the telecom regime, we observe rich nonlinear phenomena including Kerr comb generation, Brillouin lasing, and Raman lasing. Extending to the 2 μm band, we demonstrate four-wave mixing in a sub-millimeter cavity, highlighting the platform's potential for the 2 μm band mid-infrared nonlinear optics.
