Abstract

We proposed and demonstrated a novel scheme to realize wavelength-selective reconfigurable optical delay buffers using optical fiber delay in a folded-path architecture. The experimental results show that multiple wavelength 10-Gb/s dense wavelength-division-multiplexed packets with 50-GHz channel spacing can individually be delayed a variable amount of time simultaneously with a power penalty less than 1 dB using the proposed reconfigurable buffer architecture
