Abstract :
We demonstrate a tunable optical correlator for amplitude and phase modulated signals up to 4-symbol-long patterns using conversion/dispersion based delays. We observed ~1-dB sensitivity penalty (at 10-9 BER) for 2-bit correlation of a BPSK signal. Fine phase control of the taps is shown by wavelength tuning.
