An optomechanical interface bridging x-ray and optical photons — Wen-Te Liao1,2 and •Adriana Pálffy1 — 1Max-Planck-Institut für Kernphysik, Heidelberg — 2National Central University, Taoyuan City, Taiwan
Future photonic quantum networks will require interfaces between different photon frequency regimes. So far, conversion experiments bridged the visible with telecommunication bands in infrared [1,2]. Going towards shorter wavelengths bears however certain advantages: x-rays are better focusable, are more robust and penetrate deeper through materials than visible or IR photons. They also carry much larger momenta, potentially facilitating the entanglement of light and matter at a single-photon level.
Here we envisage for the first time an optomechanical system that bridges optical photons and x-rays. The x-ray-optical interface system comprises of an optomechanical cavity and a movable microlever interacting with both an optical laser and with x-rays via resonant nuclear scattering. We develop a theoretical model for this system and show that x-ray absorption spectra of nuclei can be tuned optomechanically [3]. In particular, our theoretical simulations predict optomechanically induced transparency of x-rays, which can be used for metrology-relevant applications.
