Abstract

Optical communication has proven its capabilities in fulfilling the ever increasing global desire for higher data rates for long as well as short distance communication. In order to achieve reliable communication several error detection mechanisms have so far been implemented using conventional electronics which do not match with the pace of optical processing of digital bits. In this research, implementation of the encoding of (7, 4) Cyclic Redundancy Check (CRC) code using optical method has been shown. The CRC encoder has been designed using Lithium Niobate (LiNb03) waveguide based Mach-Zehnder Interferometers (MZI). The structure simulated using beam propagation method has shown accurate encoding of the CRC code. The design parameters as well as the performance parameters have been described briefly.
基于铌酸锂波导的可靠通信电光循环冗余校验编码器设计*
光通信已经证明了它在满足全球对长距离和短距离通信的更高数据速率不断增长的需求方面的能力。为了实现可靠的通信,目前已经采用了几种与数字比特光学处理速度不匹配的传统电子技术来实现错误检测机制。在本研究中,使用光学方法实现了(7,4)循环冗余校验(CRC)码的编码。采用铌酸锂(LiNb03)波导的Mach-Zehnder干涉仪(MZI)设计了CRC编码器。用波束传播法对该结构进行了仿真,结果表明该结构可以准确地编码CRC码。简要介绍了其设计参数和性能参数。
