摘要： Matrix multiplication is performed using a photonic computing block. Matrices are preprocessed to derive representative positive, real-valued matrices. The representative matrices are multiplied using a photonic computing block in which elements of a first matrix are encoded as a signal intensity and elements of a second matrix are encoded by tuning a spectral filter to apply a corresponding weight coefficient. Pairwise multiplications of matrix elements are performed by processing different wavelength components of an overall optical signal. A balanced photodiode receives the different wavelength components following manipulation in order to complete the multiplication. A matrix multiplication can be partitioned to fit a photonic computing block. The partitions are processed in parallel by multiple photonic computing blocks then reassembled into a final matrix. The multiplication operation can be part of a matrix inversion operation. Applications include (massive) multiple input multiple output (MIMO) precoding and detection, beamforming and other wireless communication applications.

摘要： Disclosed herein is a method and a system for comparing a first optical signal and a second optical signal. The method comprises the step of generating a first copied signal that is a copy of the first optical signal centred at an optical frequency, and generating a second copied signal that is a copy of the second optical signal centred at the optical frequency, the first copied signal being π radians out of phase to the second copied signal. The method further comprises the step of interfering the first copied signal and the second copied signal to generate an optical comparison signal. Generating the copied signals may comprise coupling via a nonlinear wave mixing process the optical signals to stimulating optical waves.

摘要： The present invention relates to a method and apparatus for generating an optical bit slot window in which N bit slots having the same logical state are generated. A switching device is used which is coupled to an optical pulse source which generates optical pulses in successive bit slots, each optical pulse representing a logical state. Switching signals are then applied to a switching input of the switching device so as to selectively switch a connection between the input and an output. Consequently the logical state of the output is controlled to generate the required N bit slot window.

摘要： An optical signal processor (10) and a method of processing optical data are described. The processor (10) has at least one optical coupling unit (12) each unit (12) having two optical couplers (12A, 12B) which are connected so that the principal channels (14) are connected in series with a time delay of a predetermined value in the principal channel (14) between adjacent couplers (12A, 12B). The optical coupling units (12) are formed into stages and the number of optical coupling units (12) or stages determines further coding of each bit of the input optical signal or code sequence. In other words, if the input code is M-bits long then M optical coupler stages are required to process this code and determine whether the code matches with the preset code sequence. Stages can be coupled together to process a sequence of optical pulses corresponding in number to the number of optical coupling stages in the system and the outputs of each stage are coupled via optical switches (18) to an optical summing device (24) to simultaneously process the coded data and determine whether the processing has resulted in matching or mismatching of data.
