Abstract

In this paper we present a brief analysis of existing materials and structures with quadratic-nonlinear optical properties that can be used to generate a difference frequency in both THz and sub-THz frequency ranges. This task is actual for future hybrid radio-over-fiber systems exploiting ultra high frequencies (6G etc.). It is shown that such a device may be of interest regarding the problems of generating (preparation) quantum-entangled states of photons, which can find application in high-performance computing and information systems. It is shown that the proposed concept of nonlinear optical-to-radio converter can be applied for entangled photons preparation as well.
