Multicolor interband solitons in microcombs
Qing-Xin Ji, Hanfei Hou, Jinhao Ge +10
In microcombs, solitons can drive non-soliton-forming modes to induce optical gain. Under specific conditions, a regenerative secondary temporal pulse coinciding in time and space…
Efficient and wavelength-tunable second-harmonic generation towards the green gap
Zhiquan Yuan, Jinhao Ge, Peng Liu +7
Achieving compact and efficient visible laser sources is crucial for a wide range of applications. However traditional semiconductor laser technology faces difficulties in producin…
Technical description and performance of the phase II version of the Keck Planet Imager and Characterizer
Nemanja Jovanovic, Daniel Echeverri, Jacques-Robert Delorme +46
The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction limited, high…
All-optical computing with beyond 100-GHz clock rates
Gordon H. Y. Li, Midya Parto, Jinhao Ge +9
A computer's clock rate ultimately determines the minimum time between sequential operations or instructions. Despite exponential advances in electronic computer performance owing…
