| Abstract All-optical high-speed turbo-switches can effectively increase the switching speed using cascaded semiconductor optical amplifiers (SOAs). The overall recovery time or the bandwidth of turbo-switch was numerically analyzed with time-domain and frequency-domain SOA models. The turbo-switch was explored from the fundamental carrier dynamics in SOAs for the purpose of further increasing its operation speed. An integrated turbo-switch was also been proposed and demonstrated, where a phase adjustable Mach-Zehnder interferometer (MZI) was applied as an optical band-pass filter between SOAs. Wavelength conversion was first demonstrated at 84.8 Gbit/s using the integrated turbo-switch.Keywords semiconductor optical amplifier (SOA) all-optical signal processing high-speed switches semiconductor integration Corresponding Authors: Xuelin YANG Just Accepted Date: 19 August 2016 Online First Date: 13 September 2016 Issue Date: 28 September 2016 |
