Reconfigurable 2-D WDM Optical Tapped-Delay-Line to Correlate 20Gbaud QPSK Data

We demonstrate a 2-D optical tapped-delay-line that exploits nonlinearities and chromatic dispersion to perform 2-D correlation on 20Gbaud QPSK data with correlator results with an average EVM of ~7.8%. We successfully recognize different 2×2 target patterns in an image with 961 pixels.
