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…
Ultralow-loss spiral resonators for precise LiDAR
Osama Terra, Warren Jin, Hussein Kotb +2
Swept laser interferometry is an extremely powerful solution embedded in several recent technologies such as absolute distance measurement, light detection and ranging, optical fre…
Photonic Millimeter-wave Generation Beyond the Cavity Thermal Limit
William Groman, Igor Kudelin, Alexander Lind +11
Next-generation communications, radar and navigation systems will extend and exploit the higher bandwidth of the millimeter-wave domain for increased communication data rates as we…
Dispersive-wave-agile optical frequency division
Qing-Xin Ji, Wei Zhang, Peng Liu +10
The remarkable frequency stability of resonant systems in the optical domain (optical cavities and atomic transitions) can be harnessed at frequency scales accessible by electronic…
