|Title:||Non-degenerated sequential time-bin entanglement generation using periodically poled KTP waveguide|
|Published:||August 31, 2009|
|Abstract:||We have experimentally implemented a non-degenerate sequential time-bin entangled photon-pair source using a periodically poled potassium titanyl phosphate (PPKTP) waveguide at a clock rate of 1 GHz. The wavelengths of the signal and idler are 895 and 1310 nm, which are suitable for local and long distance optical communications, respectively. A silicon avalanche photodiode (APD) is used to detect the photons at 895 nm while a periodically poled lithium niobate (PPLN) waveguide based up-conversion detector is used to detect the photons at 1310 nm. The measured entangled-photon-pair flux rate is 650 Hz and the visibility for two-photon interference fringe is 79.4 % without noise abstraction.|
