In-line fiber optic memory

摘要: A fiber optic recirculating memory comprises a splice-free length of optical which forms loop that is optically closed by means coupler. The coupler couples an signal input pulse to the for circulation therein, and outputs portion on each provide series output pulses. pump source included with having sufficient intensity cause stimulated Raman scattering in loop, thereby amplification circulating pulse. characteristics, power are selected yield gain compensates total round-trip losses so as train constant amplitude invention may be implemented utilizing standard modulation technique. pulses duration periodicity chosen prevent overlap until at least two circulations minimizes fluctuations will therefore enhance stability.
