	Optical fiber - Wikipedia, the free encyclopedia
		Optical fiber is a cyclindrical structure that transmits light along its axis by means of total internal reflection.
		At higher optical powers, is susceptible to "fiber fuse" wherein a bit too much light meeting with an imperfection can destroy as much as 1.5 kilometers of wire at several metres per second [1][2][3][4].
		An optical fiber (also spelled fibre) is a transparent thin fiber, usually made of glass or plastic, for transmitting light.

	Optics - Wikipedia, the free encyclopedia
		Some optical phenomena depend on the quantum nature of light and as such some areas of optics are also related to quantum mechanics.
		Optical science is a part of many related disciplines including electrical engineering, physics, psychology, medicine, and others.
		The pure science aspects of the field are often called Optical Science or Optical Physics.

		Optical transmission tests were performed using programmable settings of signal and bias currents in the VCSEL drivers.
		Optical DC characterization was performed on 20 prototype samples out of which more than 90% were fully functional.

	Optical Art: Artists and their Works
		Optical Art is a mathematically-themed form of Abstract art, which uses repetition of simple forms and colors to create vibrating effects, moiré patterns, foreground-background confusion, an exaggerated sense of depth, and other visual effects.
		With Optical Art, the rules that the viewer's eye uses to try to make sense of a visual image are themselves the "subject" of the artwork.
		In the mid-20th century, artists such as Victor Vasarely, Josef Albers and M.C. Escher experimented with Optical Art.

	Optical cross-connects redefine WDM systems (September 2004) - News & Analysis - fibers.org
		The optical cross-connect is emerging as the fundamental building block of a seamless optical transport network, one in which distributed intelligence, automated circuit provisioning and rapid time-to-service are the defining characteristics.
		The dynamic optical networking interoperability testing was based on OIF implementation agreements for UNI 1.0 release 2 and E-NNI, and included testing of both the control and data plane.
		And underpinning it all is a new optical control plane that runs signalling protocols in the ONEs and integrates the entire network in terms of provisioning (circuit setup or teardown), fault-finding and outage recovery.

	Optical Communications in Space
		The MOMOT optical head is essentially a monolithic glass block which fully compensates for thermal expansion effects and supports all optical and electro-optical elements.
		Optical phased arrays provide laser communication systems with the inertia-free and hence ultra-fast, beam scanning ability needed for accurate beam pointing, efficient area scanning and reliable link tracking in the presence of spacecraft attitude jitter.
		Today, the problem of acceptance of optical free-space communication in the commercial payload market is not so much a technical one but rather the lack of its convincing in-orbit demonstration to the commercial satellite communications community.

	IBM Think Research IBM and Kymata Team to Develop Optical Chips

	optical isomerism
		Optical isomers are named like this because of their effect on plane polarised light.
		For example, one of the optical isomers (enantiomers) of the amino acid alanine is known as (+)alanine.
		When optically active substances are made in the lab, they often occur as a 50/50 mixture of the two enantiomers.

	Optical Networking - Computerworld
		At the heart of optical networking is optical fiber, which consists of a narrow thread of glass—actually pure silicon dioxide—that's been clad with another glass that has a different index of refraction.
		Optical LANs will certainly appear, but in the near future, most installations will use existing copper wire to make the final jump from the optical WAN to the LAN, the home or the end user.
		After decades of development, optical networks have emerged as feasible alternatives to traditional copper cabling or wireless networks, offering much greater capacity and higher transmission speeds along with the ability to handle multiple simultaneous transmissions.

	What is optical disk? - A Word Definition From the Webopedia Computer Dictionary
		Optical disks can store much more data -- up to 6 gigabytes (6 billion bytes) -- than most portable magnetic media, such as floppies.
		These are often referred to as EO (erasable optical) disks.
		These three technologies are not compatible with one another; each requires a different type of disk drive and disk.

	NASA scientists work to improve optical computing technology
		All-optical components will have the advantage of speed over EO devices, but there is a lack of efficient nonlinear optical (NLO) materials that can respond at low power levels.
		According to Dr. Frazier, these all-optical computer components and thin-films developed by NASA are essential to the current worldwide work in electro-optical hybrid computers - and will help to make possible the astounding organic optical computers that will be the standard of future terrestrial and space information, operating and communication systems.
		Frazier and Abdeldayem and their group in Huntsville, AL, have designed and built all-optical logic gate circuits for data processing at Gigabit and Terabit rates, and they are also working on a system for pattern recognition.
