Self-diffracting effects in hybrid materials

Abstract

The authors experimentally demonstrate self-diffraction effect in a hybrid material. Patterns at different light intensity levels were obtained. A dependence of the number of diffraction rings with the intensity of laser is observed.

High-order optical nonlinearities in plasmonic nanocomposites—a review

“…The first observation of SSPM was reported in CS 2 , illuminated by a He-Ne laser, due to refractive index modulation induced by thermal effects [115]. Subsequently, several studies were reported in media exhibiting thermal nonlinearities [116][117][118][119][120][121][122][123], Kerr-type media [124][125][126][127], photorefractive crystals [128], nematic liquid crystals [129][130][131], and a variety of other physical systems [132][133][134][135][136]. The SSPM effect in MDNCs has been studied by several authors [121][122][123][124][125][126] but only low-order nonlinearities were investigated.…”

Recent Advances in Spatial Self‐Phase Modulation with 2D Materials and its Applications

“…SSPM is an all light modulation phenomenon occurring due to Kerr nonlinearity of the nonlinear material. [25][26][27][28][29] In 1967, Callen et al reported this highly interesting nonlinear effect for the first time. [30] In 1978, Stolen et al employed SSPM to measure the nonlinear optical response of a single-mode fiber.…”

Nonlocal nonlinear refraction in Hibiscus Sabdariffa with large phase shifts

“…A large number of materials with nonlinear response have been investigated such as gold nanoparticles [1], silver nanoparticles [2], hybrid materials [3,4], liquid crystals, organic dyes [5,6], etc., determining whether its answer is local or nonlocal. Nonlocal response occurs when nonlinear mechanism involve transport processes such as heat conduction in materials with thermal nonlinearities, drift or diffusion of electric charges in photorefractive media by long-range forces or interaction of several bodies.…”
