Cascaded parametric down-conversion with seed — •Stephan Krapick, Benjamin Brecht, Vahid Ansari, Harald Herrmann, and Christine Silberhorn — Universität Paderborn, Department Physik, Warburger Str. 100, 33098 Paderborn, Deutschland
We report on the cascading of two type-I parametric down-conversion (PDC) sources, which are monolithically integrated in periodically poled lithium niobate waveguide structures. By seeding the secondary PDC stage with synchronized and strongly attenuated laser pulses, we achieve wavelength tunable, narrowband photonic states.
