Abstracts of Current Research:- Information security within optical fiber: A new optical communication system exhibiting a double security level is developed. Information coding is based on combined modulation formats of two data streams over the same optical carrier. Incoherent 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 processing. The incoherent scheme is very practical and can be implemented in existing optical communications systems, using currently available technology. Computer experiments of the incoherent method indicate less than 25 dB of SNR required for BER, and ineligible information decoding time of more than 10^8 years.
- Next generation optical WDM networks: This research is focused 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 technological capabilities are being developed: optical-level: ultrafast tunable active and passive devices, e.g., lasers and filters; theoretical 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 communication, telecom, multimedia, interactive communication (e.g., video conferencing).
