Nanometer bandwidth soliton generation and experimental transmission within nonlinear fiber optics using an add-drop filter system

Abstract

An optical add-drop filter system is used to generate ultra-short nanometer (nm) bandwidth soliton pulses to be transmitted along the nano communication nonlinear fiber optics. In order to reduce the loss during the transmission, ultra-short soliton pulses are recommended. The theoretical part of this study uses the Z-transform method to present the characteristic transmission of the optical add-drop filter system. The nonlinear refractive index of the fiber optic transmission link is 2.6×10-20 m2/W. The Wavelength Division Multiplexing (WDM) can be performed to enhance the capacity of the system. This occurs when the bigger size of the ring resonator is used. Here, soliton pulses with bandwidths of 2.1 and 0.42 nm are generated and transmitted over the fiber optic length, where signals with a bandwidth of 55 and 200 ps are successfully detected at the end of the transmission link.
