Techniques for 640 Gbit/s optical signal processing are described, including demultiplexing, clock recovery, transmission, wavelength conversion, add-drop multiplexing, and timing-jitter tolerance. Demultiplexing at 1.28 Tbit/s is presented, with preliminary results for 1.28 Tbit/s transmission.
Techniques for 640 Gbit/s generation, demultiplexing, clock recovery, add/drop multiplexing, wavelength conversion, transmission, channel identification and timing jitter tolerant switching is described. Various switching materials are explored, such as HNLF, SOA, chalcogenide, and PPLN.
This paper will present recently identified and demonstrated key technologies for ultra-high-speed serial communications. Certain key components such as stabilised highly non-linear fibre switches, periodically poled Lithium Niobate devices and semiconductor optical amplifiers will be described with demonstrations of 640 Gb/s transmission, clock recovery, demultiplexing, add/drop, wavelength conversion...
