About Us:

Biphoton Technologies specializes in building affordable polarization entangled photon sources. These sources are based on a non-linear optics process called spontaneous parametric down conversion (SPDC). In our sources, SPDC occurs inside a novel interferometer configuration that is easy to manufacture and takes the pain out of optical alignment. Source configurations (wavelength, material) vary depending on needs, but typical performance is >95% fidelity with a maximally polarization entangled state, and millions of pairs produced per mW of input pump power. If you would like to know more about these devices, or would like to discuss their suitability for your research, please contact us at info@biphoton.com
