Squeezed Light Generation by Cooper Pair Recombination in a Superconductor-Semiconductor Structure

arXiv:2611.14622v1 Announce Type: new Abstract: We theoretically demonstrate squeezed light generation in a compact, electrically driven device utilizing the nonlinear light-matter interaction of Cooper-pair recombination in a hybrid superconductorsemiconductor structure. On the basis of second-order perturbation theory, we developed an effective Hamiltonian which incorporates the electronic component of the interaction as a photon coupling strength coefficient, enabling a model to describe the quadrature squeezing effect of Cooper-pair recombination on the photonic state. We find the squeezing strength to be proportional to the superconducting energy gap squared and device length, as well as increasing with applied voltage.
