Squeezed light generation via magnetostrictive optomechanics

This paper proposes using an opto-magnomechanical system to generate a broadband squeezed optical output field. A yttrium-iron-garnet crystal links a microwave cavity and optical cavity, enabling conversion between magnon, phonon and photon modes. Magnetostrictive forces in the crystal induce quadrature squeezing of the mechanical mode, which couples to the optical field. Results show a wide, stable bandwidth of squeezing robust against thermal noise, useful for precision metrology and quantum networks.
