Phase-sensitive four-wave mixing and Raman suppression in a microstructure fiber with dual laser pumps.
On coupling two phase-coherent frequency-conjugate laser pulses into a microstructure fiber, we observe phase-sensitive photon generation via four-wave mixing, and suppression of Raman emission at the middle frequency.
