چکیده:

Consequences of utilizing Femtosecond Fibre Soliton Lasers in Optical Communication Networks are known as Modulation Instability, nonlinear optical output and period doubling route to chaotic waveform; however this provides to improve network security inasmuch as the highest network security belongs to optical chaos communication networks. This study is an attempt to model an optical network using femtosecond fibre soliton laser in order to investigate the nonlinear output characteristics; thus, firstly optical network based on fibre loop soliton laser is modelled to investigate the modulation instability in addition to theoretical approaches and then Nonlinear Schrödinger Equation is described to present a simple model for surveying the period doubling route to multiple pulsing in femtosecond mode-locked fibre lasers; the results confirm and complement the preceding studies in both cases; Finally high network security and other novel applications are explained as the features of optical network communication based on mode-locked soliton fibre lasers
