Multimode fiber (MMF) consists of a light-guiding core embedded in a cladding with a diameter of typically only 125 µm, about the thickness of a human hair. Unlike single mode fiber, which has a core ...

Researchers have synthesized a collection of nanoparticles, known as carbon dots, capable of emitting multiple wavelengths of light from a single particle. Additionally, the team discovered that the ...

Unlike existing photodetectors that construct and integrate wavelength- and/or polarization-sensitive elements in space or time to improve the detection ability (range and sensitivity), this ...

A project from the Harvard SEAS lab of metamaterials developer Federico Capasso could help address the issue of unwanted light dispersion in optical systems. This could be a particular benefit for ...

Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...
