摘要： A method and system for Optical Code Division Multiple Access (OCDMA) transmission, in which channel selection and rejection are based on dynamic self-heterodyne filtering using differential time delays applied to the data-modulated signals to code and decode the transmissions in each channel. Mach-Zender Interferometeis (24, 50, 52) having characteristic delays between their arms are a simple way of performing this coding and decoding. The technique enables the use of narrow linewidth sources (10, 22, 74) and low spectrum spreading. Consequently this technique can be used in next-generation all-optical dynamic networks allowing bandwidth sharing on the one hand, while at the same time eliminating the need for network management and optical switching. Preliminary theoretical calculations predict the system support of up to 15 channels at a data rate of 1 GHz.

摘要： A method for providing spectral and temporal stealthy information transmitted over an optical communication channel, according to which, at the transmitting side, the power spectral density of a pulse sequence bearing the information is reduced by encrypting the temporal phase of the pulse sequence. The power of the pulse sequence is spread in the frequency domain, to be below the noise level, by sampling the pulse sequence. Spectral phase encoding is used to temporally spread the pulse sequence and to prevent coherent addition of its spectral replicas in frequency domain. The resulting signal, encrypted both in time and frequency domains, is then transmitted. Spectral phase decoding is performed at the receiving side by performing coherent detection and folding all the spectral replicas of the transmitted signal to the baseband by means of sampling. The temporal phase of the signal is decrypted and the information which is delivered by the pulse sequence is decoded.

摘要： Method for efficiently increasing the capacity of an optical channel which can operate in a given data rate B, by generating N modulated data streams with a bit rate of B/N and a bit-time of N/B at the transmission end, to be simultaneously transmitted from a transmission end to a receiving end of the channel. A shift of 1/B*N between the first modulated data stream and each of its N-1 subsequent modulated data streams is generated using time delay or phase shifting and then the first modulated data stream and its shifted subsequent modulated data streams are combined into a composite multilevel signal with up to N levels and the composite multilevel signal is transmitted to a receiving end of the channel. At the receiving end, the composite multilevel signal is sampled N times during each bit-time, in order to obtain a vector with N elements at each time, such that each element has N+1 possible values and corresponds to the order of a sample. Each of the N modulated data streams are reconstructed by vectorial MLSE, preformed for each element by calculating the joint conditional PDF.

摘要： A method of collecting data points of operating modes of a tunable laser for recharacterization of the laser while installed in an application. Operation of the laser is stopped for selected time slots, during which data is acquired about the modes of the laser, similar to that acquired during conventional characterization of the laser. These time slots are spaced in such a way that do not significantly affect normal operation of the application. After enough measurements have been acquired, new working points are calculated using a known algorithm for laser characterization. The laser control tables of operating currents to the various sections of the laser are then updated for these new working points. The method ensures that a recharacterization cycle is completed in significantly less time than the typical time scale of the aging phenomena, such that the recharacterization process closely tracks the aging process in small steps.
