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…
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…
OH absorption in on-chip high-Q resonators
Lue Wu, Maodong Gao, Jin-Yu Liu +4
Thermal silica is a common dielectric used in all silicon-photonic circuits. And bound hydroxyl ions (Si-OH) can provide a significant component of optical loss in this material on…
Soliton pulse pairs at multiple colors in normal dispersion microresonators
Zhiquan Yuan, Maodong Gao, Yan Yu +7
Soliton microcombs are helping to advance the miniaturization of a range of comb systems. These combs mode lock through the formation of short temporal pulses in anomalous dispersi…
Engineered zero-dispersion microcombs using CMOS-ready photonics
Qing-Xin Ji, Warren Jin, Lue Wu +14
Normal group velocity dispersion (GVD) microcombs offer high comb line power and high pumping efficiency compared to bright pulse microcombs. The recent demonstration of normal GVD…
Flattening laser frequency comb spectra with a high dynamic range, broadband spectral shaper on-a-chip
Nemanja Jovanovic, Pradip Gatkine, Boqiang Shen +9
Spectral shaping is critical to many fields of science. In astronomy for example, the detection of exoplanets via the Doppler effect hinges on the ability to calibrate a high resol…
An all-photonic, dynamic device for flattening the spectrum of a laser frequency comb for precise calibration of radial velocity measurements
Nemanja Jovanovic, Pradip Gatkine, Boqiang Shen +9
Laser frequency combs are fast becoming critical to reaching the highest radial velocity precisions. One shortcoming is the highly variable brightness of the comb lines across the…
