   en.wikipedia.org/wiki/Photonics_Spectra

   In addition to news and feature articles, Photonics Spectra contains business reports, technology updates, reader forums, new products and literature, calendars of conferences and courses, and applications reports. Photonics Spectra has been published since 1967 by Laurin Publishing Company, Inc. in Pittsfield, MA, United States.

3. Superluminescent diode - Wikipedia

   en.wikipedia.org/wiki/Superluminescent_diode

   A superluminescent light emitting diode is, similar to a laser diode, based on an electrically driven p-n junction that, when biased in forward direction, becomes optically active and generates amplified spontaneous emission over a wide range of wavelengths. The peak wavelength and the intensity of the SLED depend on the active material ...

4. Blue laser - Wikipedia

   en.wikipedia.org/wiki/Blue_laser

   In 1992, Japanese inventor Shuji Nakamura, while working at Nichia Chemicals, invented the first blue semiconductor LED using an InGaN active region, GaN optical guide and AlGaN cladding, and four years later, the first low-power blue laser; eventually receiving the Millennium Technology Prize awarded in 2006, and a Nobel Prize for Physics ...

5. Long-range optical wireless communication - Wikipedia

   Research published in 2009, used a similar system for traffic control of automated vehicles with LED traffic lights. [43] In September 2013, pureLiFi, the Edinburgh start-up working on Li-Fi, also demonstrated high speed point-to-point connectivity using any off-the-shelf LED light bulb. In previous work, high bandwidth specialist LEDs have ...

6. Synchrotron light source - Wikipedia

   en.wikipedia.org/wiki/Synchrotron_light_source

   Especially when artificially produced, synchrotron radiation is notable for its: High brilliance, many orders of magnitude more than with X-rays produced in conventional X-ray tubes: 3rd-generation sources typically have a brilliance larger than 10 18 photons·s −1 ·mm −2 ·mrad −2 /(0.1%BW), where 0.1%BW denotes a bandwidth 10 −3 ω centered around the frequency ω.

7. Fourier-transform spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Fourier-transform_spectroscopy

   Pulsed FT spectrometry gives the advantage of requiring a single, time-dependent measurement which can easily deconvolute a set of similar but distinct signals. The resulting composite signal, is called a free induction decay, because typically the signal will decay due to inhomogeneities in sample frequency, or simply unrecoverable loss of ...
