Thermal Optical Nonlinearity of Suspension of Absorbing Particles in Liquid Crystal

Strong Cubic Optical Nonlinearity of Gold Nanoparticles Suspension in Nematic Liquid Crystal

“…[1]. In particular, embedding of absorbing nanoparicles to a LC matrix results in a strong thermal third-order nonlinearity, which is responsible for the variation of refractive index changes of the media [2]. Each particle ''works'' as effective nano-heater of a LC matrix causing decrease of the order parameter around the particles.…”
