Photonic Generation of Higher Order UWB Signals Using Optical Amplifiers

Photonic generation of UWB signals is an emerging technique as it requires no complex optical-electrical or electrical-optical conversion. There are a number of techniques employed to generate lower order UWB signals photonically. But applications that uses UWB signals demands higher order wave. Also the generation scheme should consider optimum hardware utility and inturn the reconfigurability of the components used. Considering these criteria this paper analyses the techniques of generating UWB signals using optical amplifiers. Optical amplifiers that works based on the principal of spontaneous and stimulated emission has the inherent property of reconfigurability in response to the applied bias current and its dopant concentration. Utilizing these properties this paper aims at generating higher order UWB signals using optical amplifiers.
