Efficient Optical Time Division Multiplexing Scheme Using Solition Interaction

A soliton multiplexing scheme to minimize the time-bandwidth product (TBP) is proposed. The soliton multiplexer consisting of a highly nonlinear fiber (HNLF) combines two adjacent fundamental solitons to form a composite soliton. The soliton demultiplexer consisting of a similar HNLF separates the fundamental solitons. The theoretical analysis and numerical simulation results demonstrate that this soliton multiplexing scheme offers high time-bandwidth efficiency, which makes it an attractive candidate for meeting the challenge of increasing demand on bandwidth
