Abstract
A high-efficiency multiple-pass nonlinear wavelength converter and amplitude modulator employs a variable dispersion element between adjacent passes of a nonlinear wavelength conversion process in a single nonlinear optical material substrate. When controlled by a voltage via the electro-optic effect, the variable dispersion element dynamically alters the phase matching condition of the multiple-pass nonlinear wavelength conversion process and thus modulates the laser output amplitude. When the phase mismatch between passes is completely compensated by the variable dispersion element, the multiple-pass nonlinear wavelength converter achieves its maximum efficiency.
