Publikováno v: Conference on Lasers and Electro-Optics.

Pulsed pumping of a silica microcavity is used to generate single-soliton microcombs with conversion efficiency of 54%. Analytical expressions are developed by the Lagrangian approach and applied to model the results.

Publikováno v: Web of Science

Generation of mid-infrared combs (3.3 micron band) with GigaHertz line spacing is demonstrated by interleaved difference-frequency-generation. The method, applied to a 22 GHz repetition-rate microcomb, is useful for spectral densification of sparse m
