Abstract

The gain of four-wave mixing and the gain of Raman scattering in an optical fiber are not uniform with wavelength. Through systematic experimental study, we show that in its gain spectral region, the contrast of four-wave mixing can be optimized with respect to the gain of Raman scattering, thus high photon coincidence rate and high coincidence/accidental contrast can be simultaneously obtained. We obtain a photon coincidence rate of 53.7 kHz/mW/nm with coincidence/accidental contrast of 10:1 in a 1.8 m microstructure fiber-based photon source. We also propose a method to calibrate the photon detection efficiencies from photon counting.
