Performance analysis is carried out for all optical wavelength converter based on cross-phase modulation in a HNL Fiber followed by a MZI. Analysis has been carried out to find the output converted signal and the crosstalk due to the wavelength converter. The expression for signal to crosstalk ratio and the efficiency of wavelength conversion are derived. The performance results are evaluated numerically...
Wavelength division multiplexing (WDM) in optical fiber networks has gained wide acceptance as a means to handle the ever-increasing bandwidth demands of network users. An optical add-drop multiplexer (OADM) is an important device to add or drop wavelengths and crosstalk in OADM degrades the performance of WDM system. In this article we have developed an analytical model to study the incoherent crosstalk...
In wavelength division multiplexing (WDM) optical transmission system, crosstalk due to cross-phase modulation (XPM) is one of the most significant nonlinear effect. On the other hand in a first order group velocity dispersion (GVD) compensated system, second order GVD also restricts bit rate. This paper presents an analytical treatment of XPM effect in presence of second order GVD in WDM fiber-optic...
Vertically stacked optical banyan (VSOB) networks are attractive for serving as optical switching systems due to the good properties of banyan network structures (such as the small depth and self-routing capability), and it is expected that using the VSOB structure will lead to a better fault-tolerant capability because it is composed of multiple identical copies of banyan networks. In the Extended...
The statistical impact of Coherent and Incoherent crosstalk contributions in a proposed L-WIXC configuration due to different optical propagation delay differences, bit duration etc. is analysed. Considering coherent and incoherent crosstalk analytical expressions are developed for electric field, leakage crosstalk, Bit-Error-Rate (BER) and power penalty. Besides, the effect of all crosstalk contributions...
