Architectures with Improved Signal-to-Noise Ratio in Photonic Systems with Fiber-Loop Delay-Lines
01 January 1988
The Signal-to-Noise (SNR), for cross-talk noise only, is investigated in photonic systems that use loops of optical fiber as re-entrant delay-line memory elements. Three architectural variations are shown to significantly improve this SNR: providing one extra memory element, minimizing the number of switches in a memory element that a photonic signal must traverse, and designing large systems hierarchically from smaller ones.
