Rapidly reconfigurable optical channel selector using RF digital phase shifter for ultra-fast OTDM networks

An RF photonic scheme capable of performing channel tuning among time slots in ultra-fast OTDM networks at nanosecond reconfiguration speed is described. In the demonstration, demultiplexing across ten OTDM channels from a 100Gbit/s signal stream was achieved at a reconfiguration time of 4ns with simple ECL logic control.
