Full Width at Half Maximum (FWHM) Analysis of Solitonic Pulse Applicable in Optical Network Communication

Abstract

In this paper, we propose a system of microring resonator (MRR). This system uses a laser diode input which can be incorporated with an optical add/drop filter system. When light from the laser diode feedbacks to the fiber ring resonator, the pulses in the form of soliton can be generated by using appropriate fiber ring resonator parameters and also the input power. The filtering process occurs during the propagation of the pulse within the ring resonators. The full width at half maximum (FWHM) or bandwidth characterization of the pulse can be performed using the proposed system. Results obtained have established particular possibilities from the application such as optical network communication. The obtained results show the effects of coupling coefficients and ring radius on the bandwidth of the soliton pulse, where the graph of the FWHM versus the variable parameters such as the radius and coupling coefficient are presented.
