On-Chip Neodymium-Doped Lithium Niobate Microdisk Laser with Self-Induced Pulsing
Yuxuan He, Jiangwei Wu, Xiangmin Liu +5
Rare-earth-doped materials constitute the foundation of conventional solid-state lasers, but their bulk-crystal form is inherently incompatible with photonic integration, making it…

Frequency comb up- and down-conversion in a synchronously-driven optical microresonator
Simon J. Herr, Victor Brasch, Jan Szabados +6
Optical frequency combs are key to optical precision measurements. While most frequency combs operate in the near-infrared regime, many applications require combs at mid-infrared,…

Quasi-phase-matched nonlinear optical frequency conversion in on-chip whispering galleries
Richard Wolf, Yuechen Jia, Sebastian Bonaus +5
Chip-integrated whispering-gallery resonators enable compact and wavelength-agile nonlinear optical frequency synthesizers. So far, the most flexible phase-matching technique, i.e.…
