Photonic Crystal Fibers

Photonic crystal fibers (PCFs) are microstructured optical fibers that use tiny air hole capillaries arranged in a pattern around the center of the fiber. This makes the light propagation far superior to conventional fibers, requiring fewer repeaters and less amplification over long distances. PCFs are also capable of handling high energy lasers efficiently. What is […]

Photonic Colloidal Crystals

A colloid is a suspension or dispersion of one substance inside another, typically held in place by electromagnetic fields. Examples of common colloids include, blood, milk, ink, gelatin, smoke and fog particles. Destabilizing the electromagnetic field often causes the particles to precipitate out of their suspended state. Colloidal particles can also self-assemble or crystallize into […]

Metamaterials

Metamaterials are artificially created materials that exhibit characteristics not found in natural materials. These unique properties are often derived from the nanoscale structure of the material instead of from the chemical makeup. Most current references to metamaterials deal with interesting electromagnetic properties and often photonics or opto-electronics. One of the most exciting applications in this […]
