Abstract :
We demonstrate a bright, bandwidth-engineerable, compact, quasi-phase-matched single-waveguide source generating photon pairs near 900 nm and 1300 nm. Coincidence spectra are measured for a periodically-poled KTiOPO4 waveguide for both type-0 and type-I spontaneous parametric down-conversion.
