Special Section on Recent Advances in Ultra-high-speed Photonic Devices for Next-generation Optical Fiber Communications

摘要

With the explosive growth of Internet traffic, there is a constant and pressing demand for highly efficient transmission of increasingly large amounts of data in long-haul and metropolitan networks. Ultra-high density transmission systems at 100-Gb/s rate are being widely studied for long-haul networks. In metropolitan networks, standardization activities of 100-Gb/s Ethernet are in progress, which is scheduled for 2010. To achieve high density transmission, new modulation formats are widely investigated. Accordingly, new functions are strongly demanded for devices in optical transmitters and receivers. Moreover, cost effectiveness and low-power consumption are required. The purpose of this Special Section is to review and discuss recent ultra-high speed optical device technologies for forthcoming optical networks.
