All-Optical Wavelength Division Multiplexing Buffer System Realized Using Nonlinear Optical Loop Mirror and Feedback Loop

摘要

A buffer system is one of the essential techniques for the realization of all-optical packet switching. In this paper, we propose and demonstrate an all-optical wavelength division multiplexing (WDM) buffer which is a single loop type consisting of a nonlinear optical loop mirror (NOLM) and a feedback loop. The proposed structure provides more than 40 turns of buffering for a single input pulse (1550nm, width: 20ns) and shows suitable output when extracted by an optical control pulse (1553 nm, width: 30ns).
