7.1.3 Optimizing Light Confinement and Gain in Laser Diodes
... resonator and u(ν) couples to g(ν) - we have rather complex conditions not amenable to simple analysis. Still, we have two basic options looking at the extremes: We can define the active area - or better volume - by large values of u(ν) or g(ν) - irrespective of what the other quantity does. If we c ...

Optics - Tensors for Tots
... Every point of a wave front can be considered the origin of a new circular or spherical wave, the so-called elemetary wave. The new position of the wave front results from the superposition of all of the elementary waves. The Huygens wave front is a series of concentric circles originating from the ...

... Arthur Holly Compton studied the scattering of x-rays from electrons in a graphite target in 1923. He found that the wavelength of the scattered x-ray increased as the scattering angle measured from the forward direction increased. This puzzled him since according to electromagnetic wave ideas, the ...

Thomas Young (scientist)
.jpg?width=300)
Thomas Young (13 June 1773 – 10 May 1829) was an English polymath and physician. Young made notable scientific contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. He ""made a number of original and insightful innovations""in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollion eventually expanded on his work. He was mentioned by, among others, William Herschel, Hermann von Helmholtz, James Clerk Maxwell, and Albert Einstein. Young has been described as ""The Last Man Who Knew Everything"".
