Numerically simulation of soliton OR gate with semiconductor optical amplifier-assisted delayed interferometer

摘要

Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. The performance of a soliton all-optical logic OR gate is numerically simulated at a repetition rate of 80 Gb/s. This Boolean function is realized by using a semiconductor optical amplifier (SOA)-assisted delayed interferometer (DI). The dependence of the output quality factor (Q-factor) on the soliton characteristics and SOA's parameters has been examined and assessed. The obtained results confirm that the soliton all-optical logic OR gate implemented with logical correctness, high output and clear Q-factor.
