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…
Switching dynamics of dark-pulse Kerr comb states in optical microresonators
Elham Nazemosadat, Attila Fülöp, Óskar B. Helgason +7
Dissipative Kerr solitons are localized structures that exist in optical microresonators. They lead to the formation of microcombs --- chip-scale frequency combs that could facilit…
High-Q Si3N4 microresonators based on a subtractive processing for Kerr nonlinear optics
