OPTICALLY SWITCHED LOGIC CIRCUITS

Abstract

The development of information technologies at the present stage requires the development of new, more modern and more complex electronic equipment. Devices with controllable characteristics are being increasingly introduced. A separate direction of development of such devices is the development of circuits with the possibility of switching the circuit during operation without the need for its dismantling and reassembly. One of the possible ways to effectively solve this problem is the development of optically switched circuits. Optical switching provides a number of advantages over other switching methods, the main of which are the complete absence of electrical influence of the control circuit on the controlled circuit, the simplicity of the process of rapid reconfiguration of the circuit, as well as resistance to the influence of external electric and magnetic fields. This work shows the principle possibility of creating devices with optical switching of the circuit without the need to perform dismantling and assembly operations of this device. The paper presents the results of research on a logic circuit assembled on the basis of discrete electronic components, which can be optically switched as a logical 2AND-NOT element or as a logical 2OR-NOT element.
