Consequent to the mind-boggling progress in high-speed optical telecommunications witnessed in recent times, it appeared that it would only be a matter of time before the huge theoretical bandwidth of 53 THz offered by low-loss transmission windows (extending from 1280 nm [235 THz] to 1650 nm [182 THz]) in OH− -free high-silica optical fibers would be tapped for telecommunication through dense wavelength division multiplexing techniques! In spite of this possibility, there has been a considerable resurgence of interest among researchers to develop specialty ...
