Efficient FWM-Based Wavelength Conversion in Deuterated Ultra-Silicon-Rich Nitride (USRN:D)

We demonstrate highly nonlinear devices fabricated on deuterated ultra-silicon-rich nitride (USRN D). Waveguides with nonlinear parameters as high as 166
$\mathrm{W}^{-1}\mathrm{m}^{-1}$
are used as wavelength convertors, attaining a conversion efficiency of −43.2 dB over a waveguide length of just 1 cm.
