  • Frequency Tripling / Third Harmonic Generation - Principles and Applications
    Article - 5 Jul 2013
    Third harmonic generation may be described as a process in which the frequency of a light source is tripled when it passes through a non-linear medium.
  • What is Brillouin Scattering?
    Article - 11 Jul 2013
    Brillouin scattering may be described as a phenomenon of inelastic scattering of light in a physical medium brought about by thermally excited acoustical phonons. Brillouin scattering is usually...
  • What is a Metal Halide Lamp?
    Article - 8 Oct 2013
    Metal halide lamps or metal halide arc lamps consist of a high performance arc discharge tube housed in an elliptical reflector that focuses the output into a microscopic optical train. The arc tube...
  • Construction of the Universe - Lego-like "building block" galaxies
    News - 14 Sep 2007
    The conventional model for galaxy evolution predicts that small galaxies in the early Universe evolved into the massive galaxies of today by coalescing. Nine Lego-like “building block”...
  • Optics and Photonics Plays an Important Role in Nano and Solar Technology
    News - 13 Sep 2007
    "Optics + Photonics is proceeding on the right track with its emphasis on nano and solar technologies, which are immensely important to our future," said Akhlesh Lakhtakia, Charles Godfrey...
  • What is a Fiber Optic Coupler?
    Article - 18 Jun 2013
    A fiber optic coupler may be described as an optical element that is used in fiber optic systems that have one or more input fibers and several output fibers. A coupler basically brings together two...
  • What is a Diffraction Grating?
    Article - 18 Jun 2013
    Diffraction grating comes into the picture when there is a need for separate light of different wavelengths with high resolution. A diffraction grating is a multiple slit arrangement made by etching...
  • The Brain Sees Colour Differences Rather Than the Eye
    News - 7 Sep 2007
    Colour contrast is detected much earlier in the brain than previously thought, a new study shows. Scientists at Durham University have confirmed that colour contrast is first detected by part of...
  • What is a Photodiode?
    Article - 5 Jun 2013
    A photodiode can be described as a photo detector that is capable of converting incident light into voltage or current.
  • What is Super-Resolution Microscopy?
    Article - 6 May 2014
    Resolution limits owing to light diffraction have always been a major problem in analysing microscopic images.
