Abstract :
In this letter, a variable delay optical buffer with three stage-cascaded buffer units based on nonlinear polarization rotation in semiconductor optical amplifier is demonstrated. The buffer is suitable for integration, fast reconfiguration, scalable, and easy control. With the proposed buffers, 1024-bit data are buffered more than 100 different buffering times at 2.5 Gb/s.
