A new method for making a nonlinear optical structure for frequency conversion and for using that structure for frequency conversion is described. The nonlinear optical structure is made by depositing alternating contiguous layers of gallium arsenide and aluminum gallium arsenide onto a gallium arsenide substrate. Optical frequency conversion is performed by transmitting a pump laser beam through the structure. The new method is easier to perform than prior art methods.

Multi-layer gallium arsenide-based fresnel phase-shift device for infrared wavelength conversion

A new nonlinear optical structure for frequency conversion is described. The new nonlinear optical structure is a multilayer wafer comprising alternating layers of gallium arsenide and aluminum gallium arsenide onto a gallium arsenide substrate. The new device is both more efficient and easier to make than prior art gallium arsenide crystal structures designed for nonlinear optical conversion.
