1. A device for generating triplet photons, comprising:
a substrate exhibiting a linear refractive index equal to or less than about 1.6 for at least one radiation wavelength, a waveguide disposed on said substrate and extending from a proximal end adapted to receive laser radiation from a pump source at said wavelength, said waveguide exhibiting a linear refractive index equal to or greater than about 1.8 and a third order non-linear refractive index equal to or greater than about 1×10−19 m2/W for said at least one radiation wavelength, wherein said waveguide has a maximum cross-sectional dimension in a range of about 100 nm to about 2000 nm and a length in a range from about 10 microns to about 10 centimeters.
