Nonlinear optical crystals are a class of materials that exhibit unique properties when interacting with light. Unlike conventional optical materials, which respond linearly to the electric field of ...

Nonlinear optics in tapered fibre waveguides exploits the interplay between intense light fields and the confined geometry of submicrometre-diameter fibres. Tapers, drawn from standard optical fibres ...

In the 1960s, physicists showed how light could interact with itself in intriguing ways thanks to a process known as second-harmonic generation. In the right kind of material, two photons of a certain ...

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, ...
