Fusion Splicing of Elliptical Core Optical Fibers

Publikováno v: IEEE Photonics Technology Letters. 22:1036-1038

Fusion splicing of elliptical core optical fibers is investigated in detail. A formula is derived for how the ellipticity of the mode fields contributes to splice loss. It is shown experimentally that even fibers with rather high mode field elliptici

Accurate method for determining the refractive-index profiles of planar waveguides in uniaxial media with the optical axis normal to the surface

Autor: Torben Skettrup, Torben Veng, Jesper F. Offersgaard

Publikováno v: Applied optics. 35(15)

A new method for characterization of uniaxial planar waveguides from their measured effective mode indices is presented. The theory is outlined and expressions for efficient computer analysis are given. Uniaxial waveguide samples have been made in c-
