Description

We present an optomechanical approach to particle detection using a modified Michelson interferometer, where one mirror is replaced by a thin silicon nitride membrane. The membrane’s mechanical motion, induced by particle interactions, is read out via homodyne detection of the optical signal. This setup provides high sensitivity and paves the way for a scalable network of mechanical particle detectors. Such a platform could open new opportunities for precision sensing in dark matter sector.
