Determination of the optical characteristics of infrared fiber-optic waveguides

A. V. Vasil'ev, V. G. Plotnichenko


Abstract: A description is given of the features distinguishing determination of the optical characteristics of fiber-optic waveguides in the middle infrared region. The spectral dependences are given of the overall optical losses for single-crystal two-layer fiber-optic waveguides utilizing cesium bromide and single-layer waveguides made of a chalcogenide glass of the Ge–As–Se system in an F-42 fluoroplastic polymer cladding. In the case of the latter waveguides, a study was made of the angular dependences of the radiation power distribution inside the waveguide when CO laser radiation was coupled in at different angles.
