## Figures

FIG. 1.

Experimental setup for single-photon detection at by means of frequency upconversion. FBG denotes fiber Bragg grating, WDM denotes wavelength division multiplexer, EDFA denotes erbium doped fiber amplifier, Attn denotes attenuator, and PC denotes fiber polarization controller.

FIG. 2.

(a) Spectrum of the passively mode-locked fiber laser before (in black) and after (in red) the FBG. (b) Pulse duration of the incident pump laser of 7.5 ps (Gaussian fit).

FIG. 3.

Conversion efficiency as a function of the working temperature of the PPLN chip. Inset: spectrum of the upconverted signal at .

FIG. 4.

(a) Photon counts (in red) and background counts (in black) recorded by the Si-APD as a function of the pump power. (b) Background counts over conversion efficiency ratio dependent on the pump power.
