The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...
"Our nonlinear system transmits quantum information with 94% fidelity, compared to the theoretical limit of 33% on systems using linear optical components," said Kejie Fang, an Illinois professor of ...
Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS The ability to dynamically control the nonlinear phase in optical systems is crucial. It improves flexibility, ...
