Abstract
A nonlinear wave mixing process based on four-wave mixing via cascaded second-order nonlinearities (CSN) in a χ(2) medium performed inside the spectral processing device is utilized for real-time spectrally decomposed wave (SDW) processing. The CSN arrangement consists of a frequency-up conversion process followed by a frequency-down conversion process satisfying the type-II non-collinear phase matching condition. The four wave mixing process produces a SDW that is a product of three waveforms. The spatial-temporal information exchange results in a synthesized waveform that is a time-scaled version of the spatial image, performed on a single shot basis with femtosecond-rate response time due to the fast nonlinearity.
