Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. [ 1 ] Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields , whether or not they form part of an ...
TOSLINK (Toshiba Link) [3] is a standardized [4] optical fiber connector system. [5] Generically known as optical audio, the most common use of the TOSLINK optical fiber connector is in consumer audio equipment in which the digital optical socket carries (transmits) a stream of digital audio signals from audio equipment (CD player, DVD player, Digital Audio Tape recorder, computer, video game ...
Terabit per second Photonics: All-optical processing has the potential to replace electronics in many areas of ultrahigh bandwidth communications systems. CUDOS is developing all-optical processors, using nonlinear optics, and investigating new approaches to enable much higher volumes of data to be carried per unit of optical bandwidth.
A 15-pin VGA connector for a personal computer A 21-pin SCART or JP21 connector for a television. The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of ...
In that case, the angular resolution of an optical system can be estimated (from the diameter of the aperture and the wavelength of the light) by the Rayleigh criterion defined by Lord Rayleigh: two point sources are regarded as just resolved when the principal diffraction maximum (center) of the Airy disk of one image coincides with the first ...
Optical transfer function or modulation transfer functions are thus generally two-dimensional functions. The following figures shows the two-dimensional equivalent of the ideal and the imperfect system discussed earlier, for an optical system with trefoil, a non-rotational-symmetric aberration. Optical transfer functions are not always real-valued.
As with an HFC architecture, video controllers and data-networking services are fed through a CMTS/edge router. These electrical signals are then converted to optical ones, and transported via a 1550 nm wavelength through a wavelength-division multiplexing (WDM) platform and a passive splitter to a fiber-optic micro-node located at the customer premises.
