Coupled cavity arrays are an interesting physical architecture, in which the optical coupling between their building blocks allows one to explore some exotic states of photons including the Mott insulator and the fractional quantum Hall effect. In the present work, we numerically investigate the physics of superradiance in coupled cavity systems. To this end, we use the Jaynes-Cummings-Hubbard Hamiltonian, where each cavity contains a single two-level quantum dot interacting with the confined local mode and contiguous cavities are mutually coupled by photon hopping. A diagonalization of the photonic part of the system Hamiltonian yields collective modes. We find parameter regimes, in which the exchange of photons via each of these collective modes leads to a radiactive coupling of the intercavity emitters.
