Abstract
Described are optical fibers and scanning fiber displays comprising optical fibers. The disclosed optical fibers include a plurality of mass adjustment regions, such as gas-filled regions, positioned between a central waveguiding element and an outer periphery for reducing a mass of the optical fiber as compared to an optical fiber lacking the plurality of mass adjustment regions.
Claims20
An optical fiber comprising:
- a waveguiding element extending along an axis;
- a mechanical region surrounding the waveguiding element, wherein the mechanical region is positioned between the waveguiding element and an outer periphery, and wherein the mechanical region comprises a first material having a first density;
- and
- a plurality of hollow or gas-filled regions positioned within the mechanical region, wherein the plurality of hollow or gas-filled regions comprises a plurality of rows of hollow or gas-filled elements and are arranged within the mechanical region such that the optical fiber exhibits a radially symmetric stiffness.
