A brief review on optical nonlinearity in photonic glasses is given. For the third-order, relationship between two-photon absorption and nonlinear refractive-index is considered using a formalism developed for crystalline semiconductors. Stimulated light scattering and super-continuum generation in optical fibers are also introduced. Prominent resonant-type nonlinearity in particle-embedded glasses is described. For the second-order, a variety of poling methods are summarized. Finally, it is pointed out that different photoinduced changes can appear when excited by linear and nonlinear optical processes, and the feature is related with glass structures.
