We describe a chip-scale, telecommunications-band frequency conversion interface designed for low-noise operation at wavelengths desirable common single photon emitters.Four-wave-mixing Bragg scattering in silicon nitride waveguides is used to demonstrate upconversion and downconversion between the 980 nm 1550 wavelength regions, with signal-to-background levels > 10 efficiency of ≈ -60 dB low continuous wave input pump powers (< 50 mW).Finite element simulations split-step Fourier method indicate that increased ≈10 W (produced by amplified nanosecond pulses, example) will result 25 % existing geometries.Finally, we present waveguide designs can be connect shorter (637 852 nm) quantum emitters nm.
