Whois & Analysis for photonics.com

Photonics Spectra is a monthly business-to-business (B2B) magazine published for the engineers, scientists and end users who develop, commercialize and buy photonic products.

It provides both technical and applications information for all aspects of the global industry, integrating all segments of photonics: optics, lasers, imaging, fiber optics and electro-optics as well as photonic component manufacturing, solar cell improvements, LED lighting for cars and offices, THz, EHz, UV, IR, and visible light imaging and test equipment.

The term biophotonics denotes a combination of biology and photonics, with photonics being the science and technology of generation, manipulation, and detection of photons, quantum units of light.

Photonics is related to electronics and photons.

Photons play a central role in information technologies such as fiber optics the way electrons do in electronics.

Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.

Optics usually describes the behaviour of visible, ultraviolet, and infrared light.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.

The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".

The first laser was built in 1960 by Theodore H.

Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow.

A laser differs from other sources of light in that it emits light coherently.

Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography.

Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers.

Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light.

Temporal coherence can be used to produce pulses of light as short as a femtosecond.

An optical fiber or optical fibre is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.

Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.

Fibers are used instead of metal wires because signals travel along them with lesser amounts of loss; in addition, fibers are also immune to electromagnetic interference, a problem from which metal wires suffer excessively.

Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces, as in the case of a fiberscope.

Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers.
