摘要:
A method of processing data and related apparatuses. The method relies on an optical finite impulse response (FIR) filter. This optical FIR filter comprises several delay stages having weights set in accordance with parameters of a transformation to be applied by the optical FIR filter. Each of the delay stages is configured to impose a delay matched to a given input data period corresponding to a given input sample rate. According to the method, an optical signal is coupled into the optical FIR filter. The optical signal carries a data stream of input samples encoded at the given input sample rate; the data stream represents the data to be processed. Next, output samples are collected from an output data stream carried by an output optical signal obtained in output of the optical FIR filter. A set of output samples are obtained, which are representative of processed data.
