Metamaterials and Photonic Crystals
Nonlinear optics is the branch of optics that deals with the behavior of light in nonlinear media, where the dielectric polarization responds nonlinearly to the electric field of the light. This nonlinearity leads to a range of fascinating phenomena, including frequency mixing, self-focusing, and solitons. In the context of advanced materials and their unique properties, nonlinear optics plays a critical role in enhancing optical responses and enabling new applications in imaging, telecommunications, and laser technology.
