Ultralow noise microwaves with free-running frequency combs and electrical feedforward
Takuma Nakamura, William Groman, Qing-Xin Ji +11
Optically generated microwave signals exhibit some of the lowest phase noise and timing jitter of any microwave-generating technology to date. The success of octave-spanning optica…
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…
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…
