Spectral correlation of four wave mixing generated in a photonic crystal fiber pumped by a chirped pulse

International audienceThe spectral correlation of four-wavemixing in a photonic crystal fiber pumped by a chirped pulsehas been measured usingthedispersive Fourier transform method.From statistical measurements of multiple shot-to-shot spectral measurements, the spectral correlation between the signal and idler photons revealsphysical insights into the particular portion of the pump spectrum responsible for generating the FW
