Unreferenced date December 2009 An opticallink is a communications link that consists of a single end to end optical circuit. A cable of optical fiber , possibly concatenated into a dark fiber link, is the simplest form of an opticallink. Other forms of opticallink can include single colour links over a wavelength division multiplex infrastructure, and or links that use optical amplifier s to compensate for attenuation over long distances. Other forms of optical links include free space optical communication links. Also in the railways optical is used in two forms depending upon the whether the feeding station is main or not. Thus for main stations it is sain to be long hall and for all remaining stations it is to be short hall.

orphan date July 2010 S LINK , for simple link interface , is a high performance data acquisition standard developed at CERN for collecting information from particle accelerator s and other sources. Unlike similar systems, S LINK is based on the idea that data will be collected and stored by computers at both ends of the link, as opposed to a dumb devices collecting data to be stored on a smart computer. Having a full computer at both ends allows S LINK to be very thin, primarily defining the logical standards used to feed data at high speed from the motherboards to the link hardware interfaces. S LINK started in 1995 in response to problems collecting data from the new ATLAS experiment at CERN. ATLAS was extensively instrumented with stand alone computers, which sent data via a variety of methods to be collected on various servers. S LINK was seen as a way to provide a single mechanism for forwarding the data from the collection to the link hardware with extremely low latency. Generally the S LINK hardware provided functionality that would normally be provided by networking or other drivers running on the host Central processing unit CPU , thereby tying up cycles and introducing delays. S LINK used a 32 bit bus running up to 66 MHz, allowing for throughout up to 264 megabyte MB s. The link side was typically connected to optical fibre for transmission to the collecting machines, known as the read out motherboard , or ROMB . Data could also be sent back to the front end motherboard or FEMB , typically for flow control purposes at a much lower speed.

The Skudeneshavn Randaberg Ferry was at the same time downgraded, and the Mortavika Arsv gen Ferry established as the main connection.

Optical engineering is the field of study that focuses on applications of optics . Optical engineers design components of optical instrument s such as lens optics lenses , microscope s, telescope s, and other equipment that utilizes the properties of light . Other devices include optical sensors and measurement systems, laser s, fiber optic communication systems, optical disc systems e.g. CD , DVD , etc. Because optical engineers want to design and build devices that make light do something useful, they must understand and apply the science of optics in substantial detail, in order to know what is physically possible to achieve physics and chemistry . However, they also must know what is practical in terms of available technology, materials, costs, design methods, etc. As with other fields of engineering, computer s are important to many perhaps most optical engineers. They are used with instruments, for simulation, in design, and for many other applications. Engineers often use general computer tools such as spreadsheet s and programming language s, and they make frequent use of specialized optical software designed specifically for their field. Optical engineering metrology uses optical methods to measure micro vibrations with instruments like the laser speckle interferometer or to measure the properties of the various masses with instruments measuring refraction .

Unreferenced stub auto yes date December 2009 File Optical Circulator symbol.jpg thumb Optical Circulator symbol An optical circulator is a special optical fiber fiber optic component that can be used to separate optical signals that travel in opposite directions in an optical fiber , analogous to the operation of an electronic circulator . An optical circulator is a three port device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1, but instead exits from port 3. Circulators can be used to achieve bi directional transmission over a single fiber. Because of its high optical isolator isolation of the input and reflected optical powers and its low insertion loss , optical circulators are widely used in advanced fiber optic communications communication systems and fiber optic sensor applications. Optical circulators are non reciprocal optics, which means that changes in the properties of light passing through the device are not reversed when the light passes through in the opposite direction. This can only happen when the symmetry of the system is broken, for example by an external magnetic field . A Faraday rotator is another example of a non reciprocal optical device.

Image Optical Interleaver.gif thumb 400px right Illustration of the function of an optical interleaver and de interleaver An optical interleaver is a 3 port passive fiber optics fiber optic device that is used to combine two sets of dense wavelength division multiplexing DWDM channels odd and even channels into a composite signal stream in an interleaving way. For example, optical interleaver takes two multiplexed signals with 100 GHz spacing and interleaves them, creating a denser DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25 GHz or 12.5 GHz spacing. The device can be used in a reverse direction, forming an optical deinterleaver that separates a denser DWDM signal into odd channels and even channels. See schematic diagram. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. Thus, optical interleaver can expand the number of channels per fiber, and devices and or networks can be upgraded without requiring that all devices be upgraded. Optical interleaver is based on multiple beam interference . Currently, there are two approaches to building optical interleaver 1 Step phase Michelson interferometer , and 2 birefringence Birefringent crystal networks. The former is based on Michelson interferometer combined with Gires Tournois interferometer .

For a system composed of simple lens optics lenses and mirror s, the axis passes through the center of curvature of each surface, and coincides with the axis of rotational symmetry .

Optical physics is a subfield of atomic, molecular, and optical physics . It is the study of the generation of electromagnetic radiation , the properties of that radiation, and the interaction of that radiation with matter , especially its manipulation and control. It differs from general optics and optical engineering in that it is focused on the discovery and application of new phenomena. There is no strong distinction, however, between optical physics, applied optics, and optical engineering, since the devices of optical engineering and the applications of applied optics are necessary for basic research in optical physics, and that research leads to the development of new devices and applications. Often the same people are involved in both the basic research and the applied technology development. Researchers in optical physics use and develop light sources that span the electromagnetic spectrum from microwave s to X ray s. The field includes the generation and detection of light, linear and nonlinear optics nonlinear optical processes, and spectroscopy . Laser s and laser spectroscopy have transformed optical science.
