Optical down conversion
WebDown-conversion is a nonlinear optical process by which an incident ‘pump’ photon can be split (or down-converted) into a pair of longer-wavelength daughter photons (historically called ‘signal’ and ‘idler’) in a crystal possessing a χ(2) nonlinearity, such as … Spontaneous parametric down-conversion (also known as SPDC, parametric fluorescence or parametric scattering) is a nonlinear instant optical process that converts one photon of higher energy (namely, a pump photon), into a pair of photons (namely, a signal photon, and an idler photon) of lower … See more A nonlinear crystal is used to produce pairs of photons from a photon beam. In accordance with the law of conservation of energy and law of conservation of momentum, the pairs have combined energies and … See more SPDC was demonstrated as early as 1967 by S. E. Harris, M. K. Oshman, and R.L. Byer, as well as by D. Magde and H. Mahr. It was first applied to … See more The newly observed effect of two-photon emission from electrically driven semiconductors has been proposed as a basis for more efficient sources of entangled photon … See more In a commonly used SPDC apparatus design, a strong laser beam, termed the "pump" beam, is directed at a BBO (beta-barium borate) or lithium niobate crystal. Most of the photons continue straight through the crystal. However, occasionally, some of the photons … See more SPDC allows for the creation of optical fields containing (to a good approximation) a single photon. As of 2005, this is the predominant … See more • Photon upconversion See more
