  2. Electro-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Electro-optic_modulator

    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. The modulation may be imposed on the phase , frequency , amplitude , or polarization of the beam.

  3. Optical modulators using semiconductor nano-structures

    en.wikipedia.org/wiki/Optical_modulators_using...

    An optical modulator is an optical device which is used to modulate a beam of light with a perturbation device. It is a kind of transmitter to convert information to optical binary signal through optical fiber (optical waveguide) or transmission medium of optical frequency in fiber optic communication.

  4. Coherent optical module - Wikipedia

    en.wikipedia.org/wiki/Coherent_optical_module

    The Optical Internetworking Forum in 2016 published the CFP2-ACO or CFP2 - Analog Coherent Optics Module Interoperability Agreement (IA). This IA supports a configuration where the digital signal processor (DSP) is on the main board and analog optical components are on the module.

  5. Phased-array optics - Wikipedia

    en.wikipedia.org/wiki/Phased-array_optics

    Phased-array optics is the technology of controlling the phase and amplitude of light waves transmitting, reflecting, or captured (received) by a two-dimensional surface using adjustable surface elements.

  6. Opto-electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Opto-electronic_oscillator

    The output of the photodetector is amplified and filtered and fed back to the electric port of the modulator. This configuration supports self-sustained oscillations, at a frequency determined by the fiber delay length, the bias setting of the modulator, and the band pass characteristics of the filter. It also provides for both electric and ...

  8. Electro-absorption modulator - Wikipedia

    en.wikipedia.org/wiki/Electro-absorption_modulator

    An electro-absorption modulator (EAM) is a semiconductor device which can be used for modulating the intensity of a laser beam via an electric voltage. Its principle of operation is based on the Franz–Keldysh effect, i.e., a change in the absorption spectrum caused by an applied electric field, which changes the bandgap energy (thus the photon energy of an absorption edge) but usually does ...

  9. Acousto-optic programmable dispersive filter - Wikipedia

    en.wikipedia.org/wiki/Acousto-optic_programmable...

    An acousto-optic programmable dispersive filter (AOPDF) is a special type of collinear-beam acousto-optic modulator [1] capable of shaping spectral phase and amplitude of ultrashort laser pulses. AOPDF was invented by Pierre Tournois . [ 2 ]
