Ultrafast all-optical demultiplexing performance of monolithically integrated band gap shifted Mach-Zehnder interferometer

The all-optical 80 and 160 to 10 Gbit/s demultiplexing performance of this new switching concept have been demonstrated. The key components of this interferometric switch are the band gap shifted semiconductor optical amplifiers monolithically integrated in a symmetric Mach-Zehnder interferometer.
