High‐index dielectric nanoantennas excited at Mie‐type resonances have exhibited enormous enhancement of optical nonlinearity. Such nanostructures have been actively studied by researchers in recent years. Here, a numerical analysis study of the optical Kerr effect of nanocomposites consisting of high refractive index (GaP) spheres at the wavelength of 532 nm is presented. This is done by means of...
We investigate numerically the steady-state transmission of a Gaussian beam through Fabry–Perot cavity containing liquid medium with the negative temperature nonlinearity. It is shown that multistability may appear in different ranges of the beam depending on the optical and geometric parameters of the resonator.
