Abstract
The present invention is related to an optical wave processor, employed to simultaneously perform wavelength conversion and amplitude modulation of optical waves, comprising: a nonlinear crystal substrate monolithically cascaded by a dispersion section, a nonlinear phase-matching section, and a crystal substrate section, either having a plurality of adequate edges in order to effectively deflect the interacting waves propagating in it to form optical paths longer than that of a single-pass beam or having a optical waveguide built on a first cut-surface of the nonlinear crystal substrate with a high reflector coated at the output end of the waveguide in order to reflect the forward guiding waves back into the waveguide to form a double-pass guiding path; a modulation electrode comprising a plurality of conducting electrodes fabricated on the dispersion section and used as an electro-optic phase compensator to correct the phase mismatch of the interacting waves at different paths; and a modulation voltage supply used to provide an adequate modulating voltage signal to the modulation electrode to varying the phase mismatch of the interacting waves at different paths.
