Abstract: There is provided a method to fabricate optical taps and waveguide devices in photonic crystal fibers and other fibers with hollow structures. The method involves a preparation step, where the hollow holes inside the fiber are collapsed or partially modified locally; and a waveguide fabrication step, where a femtosecond laser is focused inside the fiber and used to produce optical waveguides that interact in the region that was previously modified in the preparation step.

Abstract: A device including an optical tap and waveguide in the core and cladding of an optical fiber together with a glass ferrule that is angle polished to provide a reflection surface (with or without total internal reflection) that produces a reflection of the light tapped from the optical fiber to reach the bottom of the glass ferrule and propagate in a direction that is perpendicular to (or at least different than the direction of propagation close to) the axis of the optical fiber. The fiber waveguide may be created using an ultrafast fabrication method and the glass ferrule can itself be modified by the same ultrafast laser technique to further manipulate the light traveling inside.
