Reconfigurable radiofrequency filters based on versatile soliton microcombs
Jianqi Hu, Jijun He, Junqiu Liu +5
The rapidly maturing integrated Kerr microcombs show significant potential for microwave photonics. Yet, state-of-the-art microcomb based radiofrequency (RF) filters have required…
Nanophotonic supercontinuum based mid-infrared dual-comb spectroscopy
Hairun Guo, Wenle Weng, Junqiu Liu +6
High resolution and fast detection of molecular vibrational absorption is important for organic synthesis, pharmaceutical process and environmental monitoring, and is enabled by mi…
A nonreciprocal optical resonator with broken time-invariance for arbitrarily high time-bandwidth performance
Ivan Cardea, Davide Grassani, Simon J. Fabbri +6
Most present-day resonant systems, throughout physics and engineering, are characterized by a strict time-reversal symmetry between the rates of energy coupled in and out of the sy…
Highly efficient 4 micron light generation through fs-fiber laser driven supercontinuum in SiN waveguides
Davide Grassani, Eirini Tagkoudi, Hairun Guo +3
Directly accessing the middle infrared, the molecular functional group spectral region, via supercontinuum generation processes based on turn-key fiber lasers offers the undeniable…
