Frequency up-conversion at the single-photon level in a periodically-poled lithium-niobate waveguide

Using sum-frequency generation we fully up-convert signal photons at 1550 nm to 775 nm. Due to coupling and filtering losses at the output, overall quantum efficiency is /spl sime/3.4% with dark-count probability of 3%.
