摘　　要：The performance of a novel all-optical sampling orthogonal frequency division multiplexing （OFDM） system is proposed and analyzed. Time delays and phase shifters are used to realize all optical forward/inverse discrete Fourier transform （DFT/IDFT）. Different system configurations are tested and analyzed to op- timize the performance, including the system capacity, modulation formats, DFT/IDFT constructions, and the width of the sample pulse. The 50- and 100-Gb/s real-time all-optical sampling （AOS） OFDM systems ave investigated. All results are analyzed, and useful suggestions are offered for future high-speedThe performance of a novel all-optical sampling orthogonal frequency division multiplexing （OFDM） system is proposed and analyzed.
