The application of electro-optic effect in lithium-niobate-based Mach–Zehnder interferometer to design a 3-bit optical pseudorandom binary sequence (PRBS) generator has been proposed, which is characterized by its simplicity of generation and stability. The proposed device is optoelectronic in nature. The PBRS generator is immensely applicable for pattern generation, encryption, and coding applications in optical networks. The study is carried out by simulating the proposed device with beam propagation method.
An optical 3-bit Excess-3 code converter is demonstrated by using Mach-Zehnder Interferometers based on electro-optic effect. It is a way to represent values with a balanced number of positive and negative numbers using a prespecified number N as a biasing value.
