Analysis of all‐optical demultiplexing from 160/320 Gbit/s to 40 Gbit/s using quantum‐dot semiconductor optical amplifiers assisted Mach‐Zehnder interferometer

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. © 2010 Wiley Periodicals, Inc.
