Paper Abstract

Optical technologies represent the main bet for future communication systems. Among the others, digital subsystems for optical processing are of great interest thanks to their intrinsic properties in terms of bandwidth, transparency, immunity to the electromagnetic interference, cost, power consumption, as well as robustness in hostile environment. Key basic functions are represented by logic gate, logic function, flip-flop memories, optical random access memories, etc.. Research in this field is in its very early stages even if some interesting techniques have been already theoretically addressed and experimentally demonstrated. In this paper we review the state of the art for all-optical flip-flop including different approaches such as fiber based, semiconductor amplifier based or waveguide and micro-ring solutions. Best result will be highlighted in terms of transition speed, switching energy, complexity and power consumption. Finally our best results are discussed.
