Integrated, ultra-compact high-Q silicon nitride microresonators for low-repetition-rate soliton microcombs
Zhichao Ye, Fuchuan Lei, Krishna Twayana +3
Multiple applications of relevance in photonics, such as spectrally efficient coherent communications, microwave synthesis or the calibration of astronomical spectrographs, would b…
Overcoming the quantum limit of optical amplification in monolithic waveguides
Zhichao Ye, Ping Zhao, Krishna Twayana +3
Optical amplifiers are essential in numerous photonic applications. Parametric amplifiers, relying on a nonlinear material to create amplification, are uniquely promising as they c…
Dissipative Kerr solitons in photonic molecules
Óskar B. Helgason, Francisco R. Arteaga-Sierra, Zhichao Ye +5
Many physical systems display quantized energy states. In optics, interacting resonant cavities show a transmission spectrum with split eigenfrequencies, similar to the split energ…
High-Q Si3N4 microresonators based on a subtractive processing for Kerr nonlinear optics
Zhichao Ye, Krishna Twayana, Peter A. Andrekson +1
Microresonator frequency combs (microcombs) are enabling new applications in frequency synthesis and metrology from high-speed laser ranging to coherent optical communications. One…
