EPPS-O Entangled Photon Pair Source (O-band)

S-Fifteen Instruments Correlated Photon-Pair Source uses spontaneous parametric down-conversion (SPDC) to create a pair of polarization entangled photons at 1316nm. The unit outputs > 500kHz photon pairs per second with a high visibility of >98% and heralding ratio of >0.3. We accept custom output wavelength requests.
