AbstractIn this experimental study, the effect of dye concentration on the optical properties of red-BS dye-doped polyvinyl alcohol (PVA) thin films is investigated. Three thin film samples with different concentration of red-BS dye were prepared by spin-coating method on the glass substrate. Using transmission and reflection spectrum of films, their optical parameter such as refractive […]
AbstractIn the present work, the optical properties of a GaAs quantum wire with a parallelogram cross section are studied. In this regard, we have used the expressions for the optical properties obtained by the compact-density matrix formalism. Here, we have investigated the intersubband optical absorption coefficients and refractive index changes as a function of the […]
