Paper Abstract

The role of bistable diode laser amplifiers in optical signal processing and optical computing is discussed. A lower bound (1 pJ) on the switching energy of all-optical unguided bistable devices is obtained. Optical guided wave devices, both active and passive, promise to have the lowest switching energy. The advantages and limitations of electronic devices are presented. It is concluded that optics has important advantages over electronics in highly interconnected systems. Bistable diode laser amplifiers have the lowest demonstrated switching energy per unit gain (300 fJ) of any optical devices operating at room temperature. Application of these devices in an updatable optical crossbar switch leads to unique capabilities. Optics has significant advantages over electronics even for matrices of modest sizes (32x32).
