We develop and characterize a disordered polymer optical fiber that uses transverse Anderson localization as a novel waveguiding mechanism. This microstructured fiber can transport a small localized beam with a radius that is comparable to the beam radius of conventional optical fibers.

Metamaterials at terahertz frequencies offer unique opportunities, but are challenging to fabricate in bulk. We adapt the fabrication procedure for microstructured polymer optical fibers to inexpensively fabricate metamaterials potentially on an industrial scale. We produce polymethylmethacrylate fibers containing ~10 μm diameter indium wires separated by ~100 μm, which exhibit a terahertz plasmonic response.

Two adjacent fluids passing through a grooved microfluidic channel can be directed to form a sheath around a prepolymer core; thereby determining both shape and cross-section. Photoinitiated polymerization, such as thiol click chemistry, is well suited for rapidly solidifying the core fluid into a microfiber with predetermined size and shape.

We describe a method for the fabrication of large-area (up to 13 cm diameter) and ultrathin (as thin as 8 nm) polymer films. Instead of using a sacrificial interlayer to delaminate the film from its substrate, we use a self-limiting surface treatment suitable for arbitrarily large areas.

FAQs
Stretching can align polymer chains along the fiber axis, influencing the filament’s mechanical behavior. Greater alignment may help engineers obtain improved strength, while the selected processing conditions also affect flexibility and durability. Because chain alignment is linked to fiber structure, stretching serves as a key control step when performance requirements extend beyond simply producing a continuous filament.
The spinneret shapes the emerging polymer stream and helps establish the filament’s diameter and structure. Diameter control matters because fiber morphology contributes to the balance among strength, flexibility, durability, and specialized function. Engineers therefore treat spinneret-related design choices as part of the broader process of tailoring fibers for textiles, filtration media, scaffolds, or composite systems.
Polymer composition and processing conditions jointly influence fiber morphology and the resulting mechanical or functional properties. The material may be processed in a dissolved or molten state, then stretched or solidified under selected conditions. Adjusting these variables allows engineers to balance competing requirements such as strength, flexibility, and durability instead of relying on polymer choice alone.
A typical workflow begins by preparing the polymer through dissolution or melting, followed by forcing the material through a spinneret to form a filament. The emerging fiber is then stretched or solidified so its structure develops the intended characteristics. Engineers monitor composition, processing conditions, diameter, and morphology to connect fabrication choices with final performance.
Engineers select this approach when a continuous fiber with controlled dimensions or tailored properties is needed. Applications supported by the process include textiles, filtration media, composite reinforcement, and biomedical scaffolds. It can also produce functional fibers designed for electrical or optical performance, making the method relevant to both structural materials and specialized engineering systems.
Evaluation can focus on fiber diameter, morphology, mechanical properties, flexibility, strength, and durability, depending on the intended application. Engineers may also examine whether the fibers provide the desired electrical or optical behavior. Comparing these outcomes with the selected composition and processing conditions helps identify how fabrication decisions affect performance in the finished material system.
