Abstract
In this work, we experimentally demonstrate the generation of near-IR correlated photon pairs via Spontaneous Four-Wave Mixing (SFWM) using a 13 cm-long MNF which has air-cladding waveguide structure with sub-micron diameter [1]. Since the dispersion property of optical fiber is heavily linked to its diameter, each wavelength of pair photon can be engineerable by tapering an optical fiber to the desired diameter satisfying the phase matching condition. Here, by using the tapered-MNF with 615 nm-diameter, signal and idler photons are generated at the wavelengths of 850 nm and 632 nm, respectively, in which Si-based single-photon detector has the high quantum efficiency (Q.E.) more than 50 % for both wavelengths.
