High-efficiency photon-pair production is a long-sought-after goal for many optical quantum technologies. and coherent photon conversion (CPC) processes are promising candidates for achieving this. We show theoretically how to control coherent conversion between a narrow-band pump photon and broadband photon pairs in nonlinear optical waveguides by tailoring frequency dispersion for b... https://www.bekindtopets.com/huge-sale-Jeffers-Citronella-Aloe-All-Natural-Horse-Shampoo-mega-choice/
