Abstract
The significant information about the properties of matter can be described with the interaction between light and matter. On this subject, the effect of the applied magnetic field and structural variation on the optical
and electrical properties of circular GaAs quantum rings at the existence of Rashba spin–orbit interaction (RSOI) have
been investigated. Also the effect of Rashba spin-orbit interaction (SOI) on the gate response in a series of noninteracting one-dimensional rings connected to some leads are studied theoretically within the waveguide theory. The
presence and absence of Rashba SOI is treated as the two inputs of the AND/NAND/NOT gates. Additionally the linear
and nonlinear optical absorption coefficient (AC) and refractive index changes (RIC) are calculated by the density matrix.
