0.9-dB/m Single-Mode Silicon Nitride Nonlinear Integrated Waveguides for Continuous-Wave Wavelength Conversion

We present efficient wavelength conversion with an over-150-nm bandwidth, using single-mode
$\text{Si}_{3}\mathrm{N}_{4}$
Kerr integrated waveguides with record-low losses of
$\boldsymbol{0.9\pm 0.2\text{dB}/\mathrm{m}}$
, This enables a first-time 100-Gbps-single-channel all-optical L-to-S-band translation without amplifying signal/idler-waves for
$\chi^{(3)}$
waveguides.
