In this paper, optical properties of coupled silica disk microresonators are investigated. The spectral response and the light intensity distribution along the coupled disks were measured. It was found that the distribution depends on the particular excited resonance, which can be attributed to the formation of normal modes of the coupled resonator system. A developed theoretical model gives quantitative agreement with the experimental observations.
