Optical fiber ring 150 Gbps data storage loop and spontaneous variable-length-pattern generator

Summary form only given. In future ultra-high-speed optical networks, there will be a need for ultra-high-speed packet buffers. The highest-data-rate stored packets reported to date were 80 Gbps, discounting the 200 GHz pulsed laser. Here we report spontaneous generation and storage of 150 Gbps packets in a fiber ring, using 9:1 rational-harmonic modulation, so that the packet roundtrip time is 1616 1/9 RF periods. The loop stores up to 14545 bits at 150.01713 Gbps.
