Enhanced continuous-wave four-wave mixing using Hybrid Modulation Technique

Abstract

Dense wavelength division multiplexing mainly used in Optical fiber communication channel. Among the non-linear effect four wave mixing is generated new frequency components among existing frequency standards. Existing FWM reduction technique used for channel density and limits the capacity of Wavelength division Multiplexing systems. In this paper we have discussed the hybrid modulation techniques for Enhancements of the continuous-wave four-wave mixing conversion efficiency suppressing FWM non-linear effect in dense wavelength division multiplexing are accomplished through the application of plasma-assisted photoresist reflow to reduce the sidewall roughness of sub-square-micron-modal area
