Abstract

In one aspect, a device for generating triplet photons is disclosed, which includes a waveguide extending from a proximal end for receiving pump radiation to a distal end through which triplet photons generated via nonlinear interaction of the pump radiation with the waveguide exit the waveguide, where the waveguide is configured such that the triplet photons generated within the waveguide reach its distal end at a rate in a range of about 0.05 triplet photons/second/mW and 0.3 triplet photons/second/mW, e.g., in a range of about 0.1 triplet photons/second/mW to about 0.2 triplet photons/second/mW.
