Description 730-740
The effect of Rotation of Plane of Polarization (RoPP) on wavelength conversion-induced nonlinearity and all-optical 3R
regeneration has attracted significant attention in the quickly changing field of Dense Wavelength Division Multiplexing
(DWDM) networks, where high-capacity data transmission is critical. This paper explores the complex interactions among
RoPP, wavelength conversion, and 3R regeneration, focusing in particular on modeling and assessing the Bit-Error-Rate
(BER) and Quality-factor (Q) variations under different polarization rotational angles. In nonlinear media, the 1545 nm
Gaussian probe signal interacts with the 1554 nm CW (Continuous Wave) pump signal to cause Cross-Phase Modulation
(XPM), which is used to convert wavelengths using nonlinear polarization rotation. Our study presents a theoretical
framework that includes RoPP modulation, Variable Optical Attenuators (VOAs), Highly Nonlinear Fiber (HNLF), Clock,
and Travelling Wave SOA (TWSOA) as major components to support the possibility of using polarization manipulation to
reduce nonlinear impairments and improve network performance as a whole. Using TWSOA integrated 3R regeneration, the
results show that the highest/lowest realized quality factor is 28.89/24.54 and the lowest/highest value of Log of (BER)
is −179.35/−132.64. It finds out that 3R regeneration improves quality factor by more than 19 at a 90-degree rotational
angle, and as a result, BER is significantly decreased. Findings confirm symmetry on both sides with reference to orthogonal
polarization. The results of this study open new directions for the development of novel approaches to strategically
manipulate the polarization state of light in order to optimize DWDM network performance and overcome the problems of
nonlinearities and signal degradation in high-capacity optical communication systems.
