The role of dielectric mirrors is very important in optics. These are used for several purposes like imaging, fabricating laser cavities, and so on. The basis for the propagation of photons in dielectric mediums is the same as electrons in solid crystals. If the electrons can be diffracted by a periodic potential well, photons could also be equally well diffracted by a periodic modulation of the refractive index of the medium. This idea led to...

Optical amplifiers are indispensable in long-haul communication systems operating in a relatively broad range of electromagnetic spectra. Various forms of optical amplifiers and their advancements have been extensively discussed in the literature emphasizing the relative merits and demerits of different types of configurations and/or designs and also usefulness in specific applications. The book - Optical Amplifiers: A Few Different Dimensions...
