====== Optomechanical Transducer ======
This transducers are build to link **Microwave excitations** <-> **phonons** <-> **photons**. 
Currently mostly in forward direction.

===== Properties =====
  * Output photon shape has input photon pump shape

===== Problems =====
  * Heating from Pump laser (Phonon bath)
    * Possible Solutions
      * 2D Crystal \cite{Ren.Matheny.ea:2020}
      * Buffer Gas \cite{Qiu.Shomroni.ea:2020}
  * Low Bandwidth
