Abstract

This work proposes a method for lowering the energy of an optical impulse required to switch superconducting key elements, based on driving such a components with the use of current and optical radiation impulses with varied lengths. The investigation was conducted with the aid of numerical modelling of the superconducting switching element response for a structure composed of a thin YBa₂Cu₃O_7-x superconducting film deposited on a sapphire substrate (Al₂O₃) with a buffer layer composed of strontium titanate (SrTiO₃). It was proven that thanks to the driving with control impulses of varied lengths, it is possible to switch such elements with 1.6 - 3.5 times lower energy of the optical impulse and the current slightly higher than the critical current, as compared with the switching mechanism employing impulses with the same length.
