摘要 随着光纤通信和光网络技术的快速发展,基于光纤的光信息处理技术引起了越来越多的关注。介绍了几种基于光纤色散的光信息处理技术,包括时间透镜、基于时域展宽的光模数转换技术、光纤光栅传感器的波长解调、图像的时域串行编码技术、全光积分器、光相关器和光的时域-频域卷积等。主要介绍了这些技术的原理、近期进展和优缺点。分析了目前基于光纤色散的光信息处理技术普遍存在的困难,对其发展趋势进行了探讨。通过对模式色散和色度色散的比较,探讨了模式色散在光信息处理技术中的发展前景,并介绍了两种基于模式色散的光信息处理技术。 With the development of optical communication and optical networks, the optical data processing based on optical fiber has been investigated intensely. Several technologies of fiber dispersion based optical data processing are introduced, including time lens, time stretch based analog/digital (A/D) converter, fiber grating sensor's wavelength demodulation, serial time-encoded amplified imaging, all optical integrator, convolution and correlation. Their principles, developments, advantages and disadvantages are discussed. The potential applications of optical data processing using modal dispersion are also discussed through comparing chromatic dispersion and modal dispersion and two kinds of modal dispersion based optical data processing are introduced.
