Abstract
The invention relates to thermal expansion-balanced transverse Anderson localization optical waveguides that have reduced bowing. The optical waveguide is formed of a fiber bundle comprising at least two distinct structural elements. The low curvature of the waveguide is achieved by a net CTE modulus being close to zero, which is achieved by relocating some of the structural elements of the fiber bundle to a different quadrant of the waveguide cross-section.
Claims14
A waveguide for transmitting electromagnetic waves from a proximal end of the waveguide to a distal end of the waveguide along a transport direction extending between the proximal and distal ends comprising:
- a fiber bundle extending along the transport direction and comprising a disordered arrangement of a first structural element and a second structural element that differs from the first structural element, whereby electromagnetic waves introduced into the proximal end are confined within a cross-sectional region transverse to the transport direction due to the difference between the first structural element and the second structural element,
- wherein the fiber bundle has a curvature of 0.1 meters-1 or less.
A method of manufacturing a waveguide for transmitting electromagnetic waves from a proximal end of the waveguide to a distal end of the waveguide along a transport direction extending between the proximal and distal ends, comprising:
- determining an intended curvature of the waveguide;
- and
- manufacturing the waveguide to achieve the intended curvature.
A method of manufacturing a waveguide for transmitting electromagnetic waves from a proximal end of the waveguide to a distal end of the waveguide along a transport direction extending between the proximal and distal ends, comprising:
- forming a fiber bundle that extends along the transport direction and comprises a first structural element and a second structural element that differs from the first structural element, whereby electromagnetic waves introduced into the proximal end are confined within a cross-sectional region transverse to the transport direction due to the difference between the first structural element and the second structural element, wherein the forming step comprises arranging the first structural element and the second structural element in the fiber bundle so that the fiber bundle has a curvature of 0.1 meters-1 or less.
