单模光纤由于其极低的损耗(<；0.1dB/µS)和大的可用时间带宽积(超过10/sup 5/)，是处理微波频率信号的一种有吸引力的延迟介质。从单模光纤高效分接光的最新进展使构建能够执行各种重要信号处理功能的再循环和非再循环(分接)延迟线结构成为可能。这些功能包括编码序列生成、卷积、相关、矩阵向量乘法和频率滤波。本文介绍了单模光纤延迟线的基本特性，并回顾了近年来证明光纤延迟线器件用于宽带信号处理的可行性的实验结果。
Single-mode optical fiber is an attractive delay medium for processing microwave frequency signals due to its extremely low loss (<0.1 dB/µs) and large available time-bandwidth product (in excess of 10/sup 5/). Recent progress in the efficient tapping of light from single-mode fibers has made it possible to construct recirculating and nonrecirculating (tapped) delay-line structures that can perform a variety of important signal processing functions. These functions include coded sequence generation, convolution, correlation, matrix-vector multiplication, and frequency filtering. This paper presents the fundamental properties of single-mode fiber delay lines and reviews recent experimental results that demonstrate the feasibility of fiber delay-line devices for broad-band signal-processing applications.
