Abstract
A short-pulse measurement and detection apparatus utilizing an aperiodic non-linear quasi-phase matched (A-QPM) material. The bandwidth of the A-QPM non-linear material is such that an interaction between a first signal and a second signal occurs, facilitating measurements of signal properties by techniques such as intensity auto-correlation, intensity cross-correlation, and pulse sampling.
