Abstract

Error detection using optical parity generation has emerged as an evolving area of research in the field of optical communication networks. This paper presents the popular forward error correction technique of cyclic redundancy check (CRC) code words using the electro-optical method. CRC has served as a dominant technique to tackle multiple bit errors that occur in bursts. The structure has been designed using LiNbO3 based Mach-Zehnder Interferometer. Critical parameters such as extinction ratio (38.59 dB), insertion loss (0.043 dB), and contrast ratio (22.54 dB) have been computed and shown in the paper..
