Resonant squeezed light from photonic Cooper pairs
ORAL
Abstract
Raman scattering of photons into phonons gives rise to entangled photon pairs when the phonon emitted in a Stokes process is absorbed in anti-Stokes scattering, forming the photonic analog of Cooper pairs [1]. We present a nonperturbative theory for the time evolution of photonic Cooper pairs that treats interacting photons and phonons as a hybrid excitation, the Ramaniton. As the Ramaniton propagates in a wave guide it displays quantum oscillations between photon and phonon occupation, leading to resonant squeezed Stokes-anti-Stokes light when the phonon occupation becomes equal to zero. This phenomenon can be used to generate up to 28 dB of squeezed light even in standard silicon on insulator waveguides [2].
