Briefings

A theoretical study proposes electrically driven squeezed light generation via Cooper-pair recombination in a hybrid superconductor-semiconductor structure. The model predicts squeezing strength scales with the square of the superconducting energy gap and device length, increasing with applied voltage. Calculations indicate achievable squeezing levels comparable to existing methods when operating below the critical temperature, suggesting viability for compact integrated devices.

Key points

• Theoretical model predicts squeezed light generation via Cooper-pair recombination in a hybrid superconductor-semiconductor structure.
• Squeezing strength scales with the square of the superconducting energy gap and device length, increasing with applied voltage.

Context

This research offers a theoretical framework for electrically pumped squeezed light generation using nonlinear light-matter interactions in hybrid superconductor-semiconductor structures, potentially enabling compact integrated devices.

Limitations

The study relies on second-order perturbation theory and effective Hamiltonian development; specific device parameters, voltage bias values, and material compositions were not calculated or specified in the evidence.
