  • The Pockels Effect
    Article - 21 Jun 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 - 21 Jun 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 is Brillouin Scattering?
    Article - 21 Jun 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 Electro-Optical Rectification?
    Article - 20 Jun 2013
    Optical rectification or electro-optic rectification may be described as a non-linear optical process that generates a quasi-DC polarization in a non-linear medium by passing an intense beam of light.
  • What is Optical Phase Conjugation?
    Article - 20 Jun 2013
    Optical phase conjugation is a non-linear optical process, which is capable of time reversing the scattering process and healing the distortions in the wave front.
  • Xenon Flash Lamp - Properties and Applications
    Article - 18 Jun 2013
    Xenon lamps are ionized gas lamps that emit light in various spectral lines, when an electric current is passed through the tube.
  • What is an Optical Fiber Isolator?
    Article - 13 Jun 2013
    Optical isolators are optical elements which allow light to propagate in only one direction. The propagation of light in one single direction is required in order to prevent optical back scattering or...
  • What is a Fiber Optic Coupler?
    Article - 13 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 Dichroic Filter?
    Article - 12 Jun 2013
    Dichroic filters are filters that optic filters that are placed at an angle of 45° to the light source, causing the light to travel in a different direction. Dichroic is a Greek word meaning...
  • What is an Opto-Semiconductor?
    Article - 12 Jun 2013
    Opto-semiconductors are semiconductors that are work by absorption and emission of light. The p-n junctions are the important part of these devices. Photodiodes, LEDs, solar cells and semiconductor...
