摘要

文章简述了全光OFDM（正交频分复用）技术的发展背景及现状

并从全光连续OFDM技术和全光离散OFDM技术两大方面对全光OFDM信号的产生技术进行了综述。研究表明

全光连续OFDM技术的关键是产生平坦、稳定、正交和低相位噪声的梳状谱

全光离散OFDM技术的关键是采用光学器件和方法实现OIDFT（光离散傅里叶逆变换）和ODFT（光离散傅里叶变换）。全光离散OFDM技术与全光连续OFDM技术相比

可扩展性更强。

Abstract

This paper describes briefly the development background and present conditions of all-optical Orthogonal Frequency-Division Multiplexing（OFDM） technology and summarizes the generation technologies for all-optical continuous and discrete OFDM signals.The all-optical continuous OFDM technology generates flat

stable

orthogonal and low-phase-noise comb spectrum

while the all-optical discrete OFDM technology realizes Optical Inverse Discrete Fourier Transform（OIDFT） and Optical Discrete Fourier Transform（ODFT） by using optical devices and methods.Compared with all-optical continuous OFDM technology

all-optical discrete OFDM technology is more scalable.
