摘要Hydrogenated amorphous silicon nitride based coupled optical microcavity is investigated theoretically and experimentally. The theoretical calculation of the transmittance spectra of optical microcavity with one cavity and coupled microcavity with two-cavity is performed. The optical eigenmode splitting for coupled microcavity is found due to the interaction between the neighbouring localized cavities. Experimentally, the coupled cavity samples are prepared by plasma enhanced chemical vapour deposition and characterized by photoluminescence measurements. It is found that the photoluminescence peak wavelength agrees well with the cavity mode in the calculated transmittance spectra. This eigenmode splitting is analogous to the electron state energy splitting in diatom molecules.
