Demonstration of an optical switch based on SOA-MZI operation at 10 Gbit/s

it was demonstrated that an optical switch which was operated at 10 Gbit/s was realized using SOA's in a Mach-Zehnder(SOA-MZI) configuration, which based on cross-phase modulation (XPM) in semiconductor optical amplifier(SOA) and interference struct. An analysis was presented to describe the phase changing in SOA, which caused by optical power injected into S OA. The interference struct supplied a method to transform phase shift into amplitude. At this process, the switch window would been created. Through the simulation the switch was approved.
