Quix Quantum has added to its photonic processing chip portfolio with a version that is optimized for use at the near-infrared wavelength range (900-970 nm) compatible with quantum dot light sources such as those made with InGaAs materials. Their previous products were optimized for operation in the telecom compatible wavelengths of 1530 to 1565 nm. The chip provides similar functionality to their previous chips and has 12 input modes with a fidelity specification of 98.6% with a mean optical loss of 3.4 db/mode. An advantage of quantum dot light sources is that they have the potential of being integrated on-chip using micropillars or photonic crystals providing a potentially more scalable solution. More information about this new chip can be found in a news release posted on the Quix website here and an arXiv preprint that provides additional technical data here.
