All light is made up of waves of electromagnetic radiation. A spectroscope spreads each different wavelength to a different position within a spectrum of light. Music is digitally recorded as circular ...

Analysis has been made of a fiber-optic passive loop resonator, the heart of the gyroscope. The performance characteristics are heavily dependent on the resonator parameters, such as coupling ...

The emissive output of indicator dyes in luminescent sensors can be amplified by the addition of antenna dyes with a higher brightness. The highly concentrated antenna dye molecules absorb the ...

We have built a fiber-optic confocal reflectance microscope capable of imaging human tissues in near real time. Miniaturization of the objective lens and the mechanical components for positioning and ...

Air traffic controllers in Florida briefly lost their radar after a fiber optic line was cut, but the outage didn't appear to lead to significant disruptions like what happened after similar ...

It depends on how precisely the light is initially structured, in other words how information is encoded, and how it interacts with the fiber properties. Dr. Mathilde Hary, Postdoctoral Researcher ...
