  • 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 Optical Phase Conjugation?
    Article - 6 May 2014
    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 - 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 Dichroic Filter?
    Article - 24 Jul 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 - 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.
  • Storage of a Single Photon in a Quantum Memory
    News - 24 Jul 2007
    A series of publications in the journal Nature highlights the race among competing research groups toward the long-anticipated goal of quantum networking. In one of three papers published the...
  • New Metamaterial May Bring Better Optics
    News - 24 Jul 2007
    Engineers at Purdue University are the first researchers to create a material that has a "negative index of refraction" in the wavelength of light used for telecommunications, a step that...
  • 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...
