PROJECT TITLE :

Suppression of Inter-channel Higher Order Four Wave Mixing in Four-Mode Phase-Sensitive Parametric Wavelength Multicasting

ABSTRACT:

Part manipulation of 4-mode part-sensitive (4MPS) process was developed as a means that for suppression of high-order four wave mixing (HoFWM) terms in twin-pump driven parametric wavelength multicasting and, consequently, for reduction of inter-channel crosstalk and inter-channel interference. In contrast to the previous studies that targeted on power stabilization and conversion efficiency maximization, the investigation in this paper focuses on the evolution of the inter-channel HoFWM tones, whose suppression can be accomplished by arranging the phases of signals in an exceedingly complementary manner. In addition, broadband 4MPS multicasting with suppressed HoFWM effects over one hundred-nm bandwidth, reaching up to 12-dB suppression ratio was demonstrated.
