  2. Coherent optical module - Wikipedia

    en.wikipedia.org/wiki/Coherent_optical_module

    The technical details of coherent optical modules were proprietary for many years, but have recently attracted efforts by multi-source agreement (MSA) groups and a standards development organizations such as the Optical Internetworking Forum. Coherent optical modules can either plug into a front panel socket or an on-board socket. Coherent ...

  3. Optical heterodyne detection - Wikipedia

    en.wikipedia.org/wiki/Optical_heterodyne_detection

    Mutual coherence permits the rainbow in Newton's rings, and supernumerary rainbows. Consequently, optical heterodyne detection is usually performed as interferometry where the LO and signal share a common origin, rather than, as in radio, a transmitter sending to a remote receiver. The remote receiver geometry is uncommon because generating a ...

  4. Hanbury Brown and Twiss effect - Wikipedia

    en.wikipedia.org/wiki/Hanbury_Brown_and_Twiss_effect

    Photon detections as a function of time for a) antibunching (e.g. light emitted from a single atom), b) random (e.g. a coherent state, laser beam), and c) bunching (chaotic light). τ c is the coherence time (the time scale of photon or intensity fluctuations).

  5. Coherent anti-Stokes Raman spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Coherent_anti-Stokes_Raman...

    Coherent anti-Stokes Raman spectroscopy, also called Coherent anti-Stokes Raman scattering spectroscopy (CARS), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures of molecules as seen in Raman spectroscopy , typically the nuclear vibrations of chemical bonds.

  6. Optical phase space - Wikipedia

    en.wikipedia.org/wiki/Optical_phase_space

    Optical phase diagram of a coherent state's distribution across phase space. In quantum optics, an optical phase space is a phase space in which all quantum states of an optical system are described. Each point in the optical phase space corresponds to a unique state of an optical system.

  7. Dolinar receiver - Wikipedia

    en.wikipedia.org/wiki/Dolinar_receiver

    The Dolinar Receiver [1] is a device based upon the Kennedy receiver [2] that may be used to discriminate between two or more low-amplitude coherent states of light using displacements and adaptive measurements.

  8. Spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Spectroscopy

    Coherent or resonance spectroscopy are techniques where the radiative energy couples two quantum states of the material in a coherent interaction that is sustained by the radiating field. The coherence can be disrupted by other interactions, such as particle collisions and energy transfer, and so often require high intensity radiation to be ...

  9. Optical coherence tomography - Wikipedia

    en.wikipedia.org/wiki/Optical_coherence_tomography

    Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
