  • 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 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.
  • 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 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 a Photodiode?
    Article - 4 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 - 23 Jan 2013
    Resolution limits owing to light diffraction have always been a major problem in analysing microscopic images.
  • Multilayer Piezoelectric Actuators - Properties and Performance of Ceramic and Polymer Coated Multilayer Piezo Actuators by Physik Instrumente
    Article - 11 Oct 2009
    The patented PICMA® technology makes it possible to manufacture components with a particularly long lifetime. Decades of experience with PICMA® series in various applications show that the lifetime...
  • Breaking the Nanometer X-Ray Resolution Barrier
    Article - 15 Jan 2008
    In recent years, researchers at the U.S. Department of Energy's Brookhaven National Laboratory have overcome a major difficulty for using refractive lenses to focus x-rays.
  • X-Rays Using Zone Plate Lenses Capable of 15-Nanometer Resolution or More
    Article - 4 Jan 2008
    Progress in nanoscience and nanotechnology depends not only on examining the surfaces of materials but on microscopically examining biological organisms and material structures to identify what they...
