In this paper, we present a theoretical evaluation of curved Er 3 ‡ -doped LiNbO 3 waveguide statistical parameters. We calculate the output mean photon number, the standard deviation, the Fano factor and the statistical uctuations. Simulations are performed using the small-gain approximation and the photon statistics master equation of the linear ampli®er, transposed to the case of curved ampli®ers. The evolution of the above-mentioned device characteristics with various pump powers, waveguide lengths and signal wavelengths are also presented.
