An optical fiber loop memory can be used in a packet switched optical network to resolve the contention problems and increase the system flexibility. We report a multi-wavelength optical fiber loop memory with in-loop waveguide grating router (WGR). Bit error rate of stored packets is analyzed both experimentally and theoretically. A new refreshable multi-wavelength loop memory configuration is proposed and experimentally demonstrated. With this refreshable optical memory, which works like a DRAM (dynamic random access memory), optical signal can be stored as long as system required.
