Research Projects
Next generation optical WDM networks This research is fo-cused on an interdisciplinary effort between different research disciplines to generate the infrastructure for dynamic WDM technology, and to merge between WDM and ATM, in order to form a multi-Tbit/sec optical network. The following techno-logical capabilities are being developed: optical-level: ultrafast tunable active and passive devices, e.g., lasers and filters; theo-retical and experimental optimization of wavelength allocation according to coherent and incoherent optical crosstalk system-level: switching, signaling, control, memory, buffering, and contention resolution; network-level: support of data communi-cation, telecom, multimedia, interactive communication (e.g., video conferencing). Information security within optical fiber A new optical com-munication system exhibiting a double security level is devel-oped. Information coding is based on combined modulation formats of two data streams over the same optical carrier. Inco-herent and coherent optical encryption algorithms are proposed, and are theoretically analyzed. The optical encryption methodis transparent to data bitrates.Furthermore, it requires on line data decoding with no possibility of recording and further process-ing. The incoherent scheme is very practical and can be imple-mented in existing optical communications systems, using cur-rently available technology. Computer experiments of the in-coherent method indicate less than 25 dB of SNR required for BER, and ineligible information decoding time of more than 10^8 years.
