Abstract

Optoelectronic logic operations were successfully demonstrated by triangular-barrier optoelectronic switch (TOPS). TOPS has not only differential gain, bistable and latch characteristics simply by changing the bias voltages, but also high sensitivity and high gain. We first confirmed AND and OR operations using a single TOPS, and also realized NOT, NAND, NOR and XOR operations using dual TOPS without any optical or electrical reset signals. These logic operations by dual TOPS can be attained in the same electrical circuit configuration.
