In nonlinear optics, we always have a trade-off present, where a stronger desired nonlinear response, e.g. a phase shift is also accompanied by one or more undesired nonlinear effects, such as additional absorption.…
Electromagnetically induced transparency (EIT) uses an optical control beam to induce a narrow transparency window in a normally opaque medium. This narrow transparency window is associated with a strong slow light…
Photonic crystal devices have big potential for nonlinear optics, as they can confine light both spatially and temporally. However, a large number of nonlinear optical processes can occur in these systems, making it…
Metasurfaces based on epsilon-near-zero materials show very strong nonlinear responses and allow coupling of light to optical modes in the epsilon-near-zero thin film that are otherwise not accessible at normal…
