Here, the influence of external magnetic field on the optical absorption and refractive index changes for a parabolically confined quantum dot in the presence of Rashba spin orbit interaction have been investigated. The results are presented as a function of quantum confinement potential, magnetic field, Rashba spin orbit interaction strength and photon energy. Our results indicate the important influence of magnetic field on the peak positions of absorption coefficient and refractive index changes. For Quantum Wire, the energy dispersion relations are studied of the spin split subbands subjected to external transverse electric and magnetic fields in the presence of Rashba spin orbit interaction. For an infinite superlattice wire, it is found that the energy gaps between different subbands are shifted due to Rashba spin orbit interaction and external electric field. Here we have also investigated the influence of external electric field and magnetic field on the optical absorption of a parabolic confinement wire.
