Measurement of the second-harmonic power generated by a quasi-phase-matched (QPM) grating as a function of the frequency detuning parameter yields the Fourier transform (FT) magnitude of the complex nonlinear coefficient profile along the QPM device. This FT magnitude can be measured by tuning eithe
A novel spectral phase conjugation scheme by three-wave mixing is proposed. It is shown that a phase-conjugated and time-reversed replica of the incoming signal can be generated, if appropriate quasi-phase matching is achieved and the three-wave mixing process is transversely pumped by a short secon
