Nonlinear and quantum photonics in high-Q microresonators
Optical microresonators have the capability to trap laser light by total internal reflection for a duration higher than a microsecond. In these ultra-high Q optical cavities, the small volume of confinement, high photon density and long photon lifetime ensures a strong light-matter interaction, which can trigger various nonlinear effects such as Kerr, Raman, or Brillouin scattering. Quantum phenomena such as twin-photon generation, entanglement, and squeezing can also occur in these systems. In this talk, we discuss some of the main challenges related to the understanding of nonlinear and quantum phenomena in optical microresonators, and present as well as some of the principal applications in aerospace and communication engineering.
