Methods for making fiber waveguides include rolling a multilayer structure into a spiral structure and forming the fiber waveguide from the spiral structure. The forming includes drawing a fiber preform derived from the spiral structure.

Methods of making fiber waveguides from multilayer structures

Ionic colloidal crystals (ordered multicomponent colloids formed by attractive electrostatic interactions) may be produced by controlling the surface potential and relative size of multiple populations of colloidal particles in suspension. Such suspensions are dried or otherwise caused to precipitate out the particles in ordered arrays. The crystal structure of the arrays may be controlled by appropriate choices of particle materials, sizes, and charge ratios.

Ionic colloidal crystals

A mirror structure includes a plurality of features of a defined size. The features include alternating spatial units of a chalcogenide glass and a thermoplastic polymer, and are specifically arranged in an ordered form so that the structure is highly reflective. Thermally-assisted methods are introduced for forming such structures.

Method of forming reflecting dielectric mirrors

In general, in one aspect, the invention features an article including a high-power, low-loss fiber waveguide that includes alternating layers of different dielectric materials surrounding a core extending along a waveguide axis, the different dielectric materials including a polymer and a glass.
