Waveguide-based single-shot temporal cross-correlator

We describe a novel technique for performing a single-shot optical cross-correlation in nanowaveguides. Our scheme is based on four-wave mixing between two orthogonally polarized input signals propagating with different velocities due to polarization mode dispersion. The cross-correlation is determined by measuring the spectrum of the idler wave generated by the four-wave mixing process. © 2014 Optical Society of America OCIS codes: 070.4550 (Correlators), 070.4340 (Nonlinear optical signal processing), 230.7370 (Waveguides) References and links 1.
