Bianucci Research Group

Our research is mostly based on optical microresonators, microscopic structures that can maintain light confined within them. We interrogate them using optical fibers (that have been tapered to a diameter comparable to the wavelength of near-infrared light) and free-space lasers.

Some of the projects we are interested in are

  • Studying the optical properties of nanomaterials,
  • Designing and implementing micro-and nanophotonics devices,
  • Topological photonics,
  • Using microresonators for sensing and
  • Microresonators and quantum optics.
