Diffraction Grating Principle Wavelength Division Multiplexing
A diffraction grating is a surface with a large number of parallel, equally spaced grooves or slits. When light hits the grating, each groove acts as a source of diffracted waves. These waves interfere with each other, producing sharp bright lines (maxima) at angles that depend. In optics, a diffraction grating is a grating with a periodic structure of appropriate scale so as to diffract light, or another type of electromagnetic radiation, into several beams traveling in different directions (i. The emerging. The advent of Dense Wavelength Division Multiplexing (DWDM) has fundamentally changed the economics of core optical networks.
