Generation of Strong Parametric Fluorescence in a Highly-Nonlinear Silicon Nitride Waveguide With a Simple Pulsed Pump Source

We present the generation of strong parametric fluorescence based on the spontaneous four-wave mixing in a highly-nonlinear silicon nitride waveguide pumped by a simple C-band pulsed pump. Parametric fluorescence spanning over 100 nm with a maximum power spectral density of -25 dBm/nm is experimentally achieved.
