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.

Group-Sep13

Some of the projects we are interested in are:

  • Studying the optical properties of nanomaterials coupled to microresonators.
  • Designing and implementing micro- and nanophotonics devices.
  • Investigating ultra-sensitive biosensors (in collaboration with Microphotonics Laboratory at Ecole Polytechnique de Montreal).
  • Fast and slow light in microresonators.
  • Solid-state quantum optics.
