  • Bragg Grating - Introduction and Applications
    Article - 29 May 2014
    Fiber Bragg Grating (FBG) is a type of Bragg reflector (distributed type) that is constructed as a short segment of optical fiber to reflect light of certain wavelength and transmit the rest.
  • Bandwidth - Definition and Introduction
    Article - 20 Jun 2014
    Bandwidth is a width of a wavelength range of a specific part of the spectrum which transmits incident energy via a filter.
  • Waveguide - Definition and Applications
    Article - 30 Apr 2014
    Waveguide is an optical structure which directs the electromagnetic waves of an optical spectrum. Some of the common types of waveguides include rectangular waveguides and optical fibers.

    Article - 6 May 2014
    A Pellin–Broca prism is a type of constant-deviation dispersive prism. It is named after its inventors, Ph. Pellin, a French instrument maker and André Broca, a professor of physiological optics.
  • An Introduction to Optical Harmonics
    Article - 5 Aug 2014
    Non-linear crystals are the materials in which dielectric polarization exhibits a non-linear response with respect to the electric field of the light.
  • Primary and Secondary Principal Planes
    Article - 29 Sep 2014
    The principal planes are two hypothetical planes found in a lens system at which all the refraction is deemed to occur.
  • Catadioptric System Definition and Applications
    Article - 6 May 2014
    Catadioptric systems may be defined as optical systems that make use of lenses and mirrors for the formation of images.
  • The Pockels Effect
    Article - 15 Aug 2013
    Pockels effect explains the influence of an electric field on a non-linear material in causing birefringence or altering the existing birefringence.
  • What is Optical Cross-Phase Modulation (XPM)?
    Article - 8 Oct 2013
    Optical cross phase modulation (XPM) may be described as a non-linear optical process where the wavelength of one light source affects the phase of another wave.
  • What are Optical Flats?
    Article - 6 May 2014
    Optical flats can be described as an optical grade glass which is polished and made extremely flat on both surfaces, used for determining the flatness of various optical surfaces.
