Efficient signal communication uses photons. Signal processing, however, an optically inactive medium, electrons. Therefore, interconnection between electronic processing and optical is required at the integrated circuit level. We demonstrated control of exciton fluxes in excitonic circuit. The consists three optoelectronic transistors performs operations with fluxes, such as directional switching merging. Photons transform into excitons input, photons output. flux from input to output controlled by a pattern electrode voltages. direct coupling photons, used communication, excitons, device-operation may lead development efficient exciton-based devices.
