A multimode optical fiber in which the refractive index of the core declines from its highest value at the center of the core to a value at the edge of the core that equals the refractive index of the ...

A singlemode optical fiber designed to reduce chromatic dispersion. The fiber core is fabricated in several layers with different refractive indices running in parallel throughout its length.

An electrical engineer and a biomaterials engineer have joined their expertise to develop a flexible, biodegradable optical fiber to deliver light into the body for medical applications. In Penn State ...
