摘要

The performance of ultrafast all-optical demultiplexer using quantum-dot semiconductor optical amplifiers (QD-SOAs) assisted Mach-Zehnder interferometer (MZI) is analyzed. Through numerical simulations, a set of key parameters are optimized and all-optical demultiplexing from 160/320 Gbit/s to 40 Gbit/s can be realized with fairly high performance. The results are useful for the system performance studies and practical application.
