Abstract

The method of an effective control of superconductor optoelectronic devices by commonly used current and optical radiation pulses is proposed. Numerical modeling of the resistive responses has been conducted for thin film structures based on high-T_c superconductor (HTS) YBa₂Cu₃O_7-x. As a results of calculations, the control characteristics of HTS-switches in the form of switching time dependences on the control mode were obtained. On the basis of this, threshold characteristics of switching and optimal control characteristics of investigated elements were obtained. It is shown that applying of together acting current and laser radiation allows to effective switching of HTS-elements with significantly decreased pulses' amplitudes. Reduction of current amplitude lets to avoid thermal instability and reduction of needed radiation flux allows to apply semiconductor lasers.
