11Optical parametric oscillator — Infrared optical parametric oscillator An optical parametric oscillator (OPO) is a parametric oscillator which oscillates at optical frequencies. It converts an input laser wave (called pump ) into two output waves of lower frequency (ωs,ωi) by… …
12Optical link — An optical link 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 optical link. Other forms of optical link can… …
13Optical chopper — An optical chopper is a mechanical device which periodically interrupts a light beam. Three types are available: variable frequency rotating disc choppers, fixed frequency tuning fork choppers, and optical shutters. A rotating disc chopper was… …

15Quantum amplifier — In physics, the term quantum amplifier may refer to any device, which use some non classical (quantum) effects for amplification of signal. In this sense, the active element of an optical laser can be considered as quantum amplifier.The weak… …
16Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
17Erbium-doped waveguide amplifier — An erbium doped waveguide amplifier (EDWA) is an optical amplifier that uses a waveguide to boost an optical signal, analogous to an erbium doped fiber amplifier (EDFA).External links* [http://www.pcmag.com/encyclopedia term/0,2542,t=EDWA i=42398 …
18Single-mode optical fiber — In fiber optic communication, a single mode optical fiber (SMF) is an optical fiber designed to carry only a single ray of light (mode). This ray of light often contains a variety of different wavelengths. Although the ray travels parallel to the …
19Lock-in amplifier — A lock in amplifier (also known as a phase sensitive detector) is a type of amplifier that can extract a signal with a known carrier wave from extremely noisy environment (S/N ratio can be as low as 60 dB or even lessFact|date=December 2007). It… …
20List of optical topics — Probably some Wikipedia articles on topics in optics are not yet listed on this page. If you cannot find the topic you are interested in on this page, the article may nonetheless exist; you can try to find it using the Search box, or look in and… …
