Abstract
A method for manufacturing a multifunctional electromagnetic waveguide from a tapered optical fiber is provided. The method involves mounting the optical fiber on a roto-translational handling apparatus, forming a first mask on a tapered section of the optical fiber to define a shape of an optical window, forming a first metal layer around the tapered section leaving a lateral edge of the first mask uncovered, removing the first mask by chemical etching to uncover the optical window, depositing a first transparent layer around the tapered section, depositing a second metal layer around the first transparent layer, forming a second mask that defines a shape of a conductive track, removing the second metal layer by chemical etching, and removing the second mask by chemical etching to uncover the conductive track.
