Characterization of high-purity, pulsed squeezed light at telecom wavelengths from pp-KTP for quantum information applications

We characterize a pp-KTP crystal designed to produce pure single mode squeezed vacuum at 1570 nm. Measurements show Hong-Ou-Mandel interference with 97% visibility and a circular joint spectral distribution with a Schmidt number of 1.08.
