Abstract
Optical multilayer structures for harmonic laser emission are disclosed. The multilayer structures are made of plurality of layers of different optically nonlinear semiconductor materials. The thicknesses, locations and refractive indices of the layers are designed, according to a modified Fourier transform, to give a broad bandwidth for interaction of fundamental light fields. Various applications are envisioned and described, e.g. spectrometers, non-blocking switching systems, wavelength division multiplexing fiber optic receivers etc.
