Fast tunable parallel optical delay line for communication and dynamic bandwidth allocation

Here we demonstrate that the fast tunable parallel optical delay line (FTDL) may be used to achieve high speed switching between optical time division multiplexing (OTDM) channels with multiple bit rates and explain how this capability can be used to implement dynamic bandwidth allocation (DBA). These capabilities can provide enhanced functionality to high speed LANs and optical interconnects. This is also useful for local area networks and metro area networks that support users that have different service demands.
