Electronic Metamaterials with Tunable Second-order Optical Nonlinearities
Hung-Hsi Lin, Felipe Vallini, Mu-Han Yang +6
The ability to engineer metamaterials with tunable nonlinear optical properties is crucial for nonlinear optics. Traditionally, metals have been employed to enhance nonlinear optic…

Observation of second-harmonic generation in silicon nitride waveguides through bulk nonlinearities
Matthew W. Puckett, Rajat Sharma, Hung-Hsi Lin +3
We present experimental results on the observation of a bulk second-order nonlinear susceptibility derived from both free-space and integrated measurements in silicon nitride. Phas…

Non-degenerate 2-photon excitation in scattering medium for fluorescence microscopy
Mu-Han Yang, Maxim Abashin, Payam A Saisan +4
Non-degenerate 2-photon excitation (ND-2PE) of a fluorophore with two laser beams of different photon energies offers an independent degree of freedom in tuning of the photon flux…
