61Apodization — literally means removing the foot . It is the technical term for changing the shape of a mathematical function, an electrical signal, an optical transmission or a mechanical structure. An example of apodization is the use of the Hann window in… …
62Microphotonics — is a branch of technology that deals with directing light on a microscopic scale. It is used in optical networking. Microphotonics employs at least two different materials with a large differential index of refraction to squeeze the light down to …
63Mandrel wrapping — In multimode fiber optics, mandrel wrapping is a technique used to preferentially attenuate high order mode power of a propagating optical signal. Consequently, if the fibre is propagating substantial energy in affected modes, the modal… …
