Variable Slowlight Buffers in All-Optical Packet Switching Routers

Abstract
We investigated variable slowlight buffers consisting of 8 and 32 tunable-coupled-resonator-rings. Experiments showed error-free operations exhibiting variable delays of 0~2 ns at 1.25 Gb/s for 8-ring and 0-350 ps at 10 Gb/s for 32-ring structures.
