In optical packet switching networks, there are some limitations on the number of wavelength converters and the number of wavelengths which can be handled at edge nodes. Therefore, the packet loss tends to occur frequently at a certain hot-spot egress node. In this paper, we propose a novel method that reduces frequency of wavelength conversions on egress node by intentionally and adaptively converting wavelength on next-to-last nodes in order to improve loss probability. Its performance is evaluated by simulations.

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 and channel identification. Timing jitter tolerance is addressed through techniques to create flat-top pulses.

Nonlinear effects in optical fibres have many attractive features and a great, not yet fully explored potential in optical signal processing.

We propose and demonstrate the use of optical signal processing to enhance the security of data networks. Optical steganography is used to inhibit the observation and analysis of data traffic. With the use of optical CDMA, service interruption is prevented in the presence of infrastructure attacks. The soft blocking capability provides protection paths without the need of permanently reserving the bandwidth. Optical CDMA also provides a large size of code set that reduces the probability of interception of the secure signal by an eavesdropper. Finally, all-optical data encryption is demonstrated that prevents side-channel attacks and enables real-time encryption.
