A novel all-optical sampling orthogonal frequency division multiplexing (AOS-OFDM) scheme with optical cyclic postfixes (OCP) inserted is proposed and demonstrated. Ultra short pulses are used as optical samples and processed by forward and inverse discrete Fourier transform (DFT/IDFT) modules in op...
