When light is squeezed down to subwavelength dimensions, the local symmetries of nanophotonic structures come to the fore and play a decisive role. Anisotropy enables new interesting regimes of operation and novel functionality, including hyperbolic modes and topological transitions, novel physics of moiré patterns, spin-orbit locking, enhanced valley polarization and chirality. The rotation and translation symmetries of optical structures enable nonradiative and nonscattering modes with unboundedly large radiative Q-factor, which can be controlled by symmetry breaking. The luck of time-reversal symmetry enables nonreciprocity and isolating devices in classical and quantum realms. In this talk, I will discuss how nanophotonics with broken symmetries heralds a new era of light and quantum technologies.
