- Abstract
As a result of the development of advanced semiconductor-based optical switching devices and their commercialization, concepts and technologies in all-optical signal processing have evolved significantly in the past few years. Universal gates are required for the realization of logical processes in photonic computing. In this study, a straightforward and small-footprint all-optical NAND gate was created utilizing semiconductor optical amplifier and simulated at high data rates between 10 to 40 Gbps. Numerical analysis of the performance of the suggested NAND gate for various input combinations and semiconductor optical amplifier (SOA) is shown. A numerical study is carried out by varying the wavelength, injection current, confinement factor, and optical elements such as sources, amplifiers, and filters. Unique results were obtained at a 10 Gbps to 40 Gbps data rate for NRZ-L user-defined bit sequences. This type of all-optical NAND gate will be the perfect alternative in the field of all-optical computing to realize a high-speed optical communication network. An extinction ratio of 15.323 dB is achieved at a high data rate of 40 Gbps. The output spectrum of the designed NAND logic is also obtained for a wide input spectrum and the system responds selectively to the input wavelength at 1548.3 nm, which is the probe signal wavelength.
