Thermal nonlinear effects in exotic media: application to the study of nonlinear interfaces.
Nonlinearities reported as self-focusing in exotic media such as green Chinese tea are identified as thermal selfdefocusing. These large index changes can be used to study hysteresis, power-induced self-switching and cross-switching, the power-induced lensing effect, and other nonlinearities at interfaces.
