| We introduce the ray model for coupled optical microdisks, where we select coupling-efficient rays among the splitting rays. Using the ray model, we report island structures arising from coupling between two microdisks and calculate the stabilities and decay rates of the island structures. We also find many resonances relating to the island structure in coupled optical microdisks and study how the island structures have an effect on the spectral properties of resonance, especially, such as distribution of loss which is represented as imaginary part of complex resonance. |
