Entangled photons are key to the development of optical quantum technologies, such as enhanced metrology, information, and communication. Chromacity has demonstrated entangled photon sources at shorter wavelengths in the visible region through our second and third harmonic generation modules. This has a number of key advantages:
i) the two-step process avoids interference from pump wavelength
ii) the peak of detection efficiency for APD is close to 690nm
Entanglement has been quantitatively verified by measuring violation of the Clauser-Horne-Shimony-Holt Bell’s inequality.

The Chromacity 1040 is an ideal source to generate a cost-effective near-infrared supercontinuum by focusing ultrashort pulses into non-linear materials, such as photonic crystal fibres.
The high energy per pulse, free-space beam from the Chromacity 1040 is ideally suited for coupling into optical fibres. Unlike solid-state lasers, which tend to produce beams with an elliptical cross-section the Chromacity 1040’s output originates from a single-mode fibre, so it is perfectly symmetric. Light from the Chromacity 1040 can be coupled into commercially available photonic-crystal fibres with efficiencies of greater than 75%. The 4-wave mixing effect that takes place within the fibre can generate supercontinuum and Raman solitons.
