Numerical Simulation of an Optoelectronic Multi-Response Device to Thermal, Electrical and Optical Stimuli Based on VO2 Thin Film

Abstract

Using numerical approaches and signal processing a group of results is obtained that allows the simulation of the behavior of an optoelectronic device, based on thin lms of vanadium dioxide, in response to electric, thermal and optical inputs. In the analysis are considered the relations among the inputs of direct voltage, temperature and energy of the incident electromagnetic radiation and the corresponding outputs of current intensity, electric resistivity and coefcient of absorption of the incident radiation. In each case the corresponding characteristic and the frequency response of the device are obtained, as well as the digital circuit that simulates the behavior of the system.
