Abstract

The converter of the invention essentially comprises, along the path of the microwave signal to be measured, a series of superconducting loops spaced apart by x/2 and each having a critical current junction facing which an optical waveguide is placed. Each of these loops absorbs, as the case may be, a bit of the wave to be measured, their inductances following an increasing geometric progression of common ratio 2 and their critical currents following a decreasing geometric progression of common ratio ½.
