| Résumé | In this paper we describe an upconversion detector in the mid infrared (around 3.5 mu m). We take advantage of the PPLN ridge waveguide technology to achieve single photon detection at room temperature on a single spatial mode. With a pump power of 192 mW we obtain a detection efficiency of 0.4% for 22k dark count per second, which corresponds to a noise equivalent power of 3 : 0 fW.Hz(-1/ 2) and an internal conversion efficiency of 85 %/W of pump.
