Four-wave mixing (FWM) was demonstrated using polymer-coated Iron phosphorus trisulfide (FePS₃) arc-shaped fiber as a device for nonlinear application. The FWM-based system had a maximum FWM conversion efficiency and wavelength tuning range of −37.5 dB and 6 nm, respectively. The FWM-based laser output was highly stable, with a maximum fluctuation in FWM conversion efficiency of only 0.1 dB. The overlaying of low refractive index (RI) polymer on the FePS₃ arc-shaped fiber enhanced the device’s performance, with an effective nonlinear coefficient, \(\gamma\), of the device was calculated to be 666.7 W^− 1 km^− 1. The proposed nonlinear device is an exciting device for integration in optical network applications.
