| Abstract: | A scheme to generate multi channel photon pairs is presented,based on a periodically poled (PP) Potassium Titanyl Phosphate (KTP) waveguide via spontaneous parametric downconversion (SPDC). Type II and type I phase matching cases with a pulsed and a cw pump laser are discussed respectively. It is analytically shown that several photon pairs could be generated in a single type II PPKTP waveguide, and the wavelengths of all photon pairs are in the telecom band. In type I case, several photon pairs can be prepared, but one photon of each pair is not in telecom band.And,a multi channel photon pairs source could be realized. |
