Abstract
We experimentally demonstrate a tunable optical correlator to search for multiple patterns among QPSK symbols in 20 Gbuad stream. We use an optical frequency comb to generate coherent signals and add them coherently using a single PPLN waveguide. Multiple patterns with different lengths are successfully searched on QPSK signals.
