Pseudo noise sequence generator based on cascaded Mach-Zehnder interferometer

An optical pseudo noise sequence generator based on Mach-Zehnder interferometer (MZI) is proposed. The device consists of MZI and a feedback line. Operability of the proposed device is simulated for continuous wave signals of 1.5 micrometer wavelength. The simulated results shows that all possible sequences of four bit pseudo noise sequence can be generated using proper arrangement of the MZI structures. The operation is numerically analysed and simulated results are discussed. Moreover, various parameters affecting performance of the device are also discussed. The proposed sequence generator can be utilized for different applications in optical wireless communication technology. © 2023 Walter de Gruyter GmbH, Berlin/Boston 2023.
