SpletA single-polarization solid-core anti-resonant fiber is proposed, and the influence of the fiber core material anisotropy of the solid-core anti-resonant fiber on polarization characteristics is investigated using the finite element method. Single-polarization guidance is achieved by using the anisotropy of optical fiber materials, which also ensures high birefringence. The … Splet04. jun. 1998 · Optical interband absorption between confined carrier states is studied in PbTe/Pb 1−x Eu x Te multiple quantum wells (MQWs). The frequency dependence of the refractive index is calculated by the Kramers–Kronig transformation of the absorption coefficient of the MQWs. It is shown that the observed interference fringes in …
