A quantum chaos study on the localization of light in a resonator-based photonic crystal

We explore the issue of eigenstate localization in a two-dimensional photonic resonator lattice. In the system of our purpose, by harmonically modulating coupling constants between the resonators an effective magnetic field is imposed on the motion of a photon. From the study on the spectral fluctuantions and participation ration of eigenstates we proceed our aim. We find that the localization properties of the studied system do not change significantly in the region of small phases. In this regime a strong delocalized character is revealed. Conversely, for larger phases a great tendency to localization is seen.
