  2. Electro-optical sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-optical_sensor

    An optical sensor can measure the changes from one or several light beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output. An optical switch enables signals in optical fibers or integrated optical circuits to be switched selectively between circuits ...

  3. Electro-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Electro-optic_modulator

    An electro-optic phase modulator for free-space beams An optical intensity modulator for optical telecommunications. An electro-optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an electro-optic effect is used to modulate a beam of light.

  4. Electro-optics - Wikipedia

    en.wikipedia.org/wiki/Electro-optics

    Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials.

  5. Electro–optic effect - Wikipedia

    en.wikipedia.org/wiki/Electro–optic_effect

    The electro-optic Pockels effect in nonlinear crystals (e.g. KDP, BSO, K*DP) can be used for electric field sensing via polarisation state modulation techniques. In this scenario, an unknown electric field results in polarisation rotation of a laser beam propagating through the electro-optic crystal; through inclusion of polarisers to modulate ...

  6. Optoelectronics - Wikipedia

    en.wikipedia.org/wiki/Optoelectronics

    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 ...

  7. Microoptoelectromechanical systems - Wikipedia

    en.wikipedia.org/wiki/Microoptoelectromechanical...

    Microoptoelectromechanical systems (MOEMS), also known as optical MEMS, are integrations of mechanical, optical, and electrical systems that involve sensing or manipulating optical signals at a very small size. MOEMS includes a wide variety of devices, for example optical switch, optical cross-connect, tunable VCSEL, microbolometers.
