Summary
We developed colorful, all-polymer Bragg fibers using polymethyl methylacrylate (PMMA) and polystyrene (PS). Adjusting layer thickness tunes the visible bandgap, enabling adjustable color in these novel polymer optical fibers.
Area of Science:
- Materials Science
- Polymer Science
- Optics
Background:
- Bragg fibers utilize periodic multilayer structures for optical properties.
- All-polymer structures offer advantages in flexibility and cost.
- Controlling the optical bandgap is crucial for photonic applications.
Purpose of the Study:
- To fabricate and characterize solid-core all-polymer Bragg fibers.
- To demonstrate tunable bandgap positioning within the visible spectrum.
- To explore the coloration properties and potential applications of these fibers.
Main Methods:
- Fabrication of multilayer polymer structures using polymethyl methylacrylate (PMMA) and polystyrene (PS).
- Characterization of optical properties, including bandgap tuning via layer thickness modification.
- Assessment of coloration in transmission and reflection modes.
Main Results:
- Successful fabrication of solid-core all-polymer Bragg fibers.
- Demonstrated tunability of the bandgap position in the visible spectrum by altering reflector layer thickness.
- Observed intense coloration of the fibers in both transmission and reflection.
Conclusions:
- All-polymer Bragg fibers offer a viable platform for tunable optical properties.
- The demonstrated color tunability opens possibilities for aesthetic and functional applications.
- These fibers show potential for use in various optical devices and decorative elements.

00:55Fibrous Proteins
Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
01:22Fiber Reinforced Concrete
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:14Generation of Straight or Branched Actin Filaments
The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

01:11Fibril-associated Collagen
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
