  • Optical Cavity - Definition, Properties and Applications
    Article - 1 May 2014
    An optical cavity or an optical resonator may be described as an arrangement of mirrors that produce a standing light wave resonator.
  • Exploring the Molecular Nature of Memory with Imaging Technology
    Article - 9 Sep 2014
    Wei Min, Assistant Professor at Columbia University and his team have investigated the synthesis of protein at a specific site in the tissue of the brain using a new imaging technique in order to...
  • What is Optical Parametric Amplification (OPA)?
    Article - 6 May 2014
    Optical parametric amplification (OPA) may be described as a process of amplifying an input signal in the presence of a higher-frequency pump wave. Apart from signal amplification, an idler wave is...
  • Sum Frequency Generation - Non-Linear Optics for Advanced Spectroscopy
    Article - 8 Oct 2013
    Sum frequency generation (SFG) may be defined as a second order non-linear optical process in which a tunable infrared beam is combined with a visible beam, such that that the frequency of the output...
  • 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 is an Optical Fiber Isolator?
    Article - 22 Oct 2014
    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 Beam Dump?
    Article - 21 Jun 2013
    A beam dump maybe defined as a device used for absorbing the energy from photons or other particles.
  • What is an Optical Amplifier?
    Article - 10 Jun 2013
    Optical amplifiers are devices that amplify an optical signal without converting it into an electric signal. Optical amplifiers are of two kinds: laser amplifiers and feedback amplifiers. Laser...
  • Gallium Indium Arsenic Antimony Lasers – Properties and Applications
    Article - 25 Apr 2014
    The gallium indium arsenic antimony lasers are diode lasers that emit infrared wavelengths. These laser diodes are important sources of lasers that generate wavelengths more than 2 µm.
