Effects of interface reflection on the resonant condition for a microcavity with multilayers between cavity mirrors

Abstract

The effects of the interface reflection on the resonant condition for a microcavity (MC) have been investigated by employing an optical model based on the transfer matrix method (TMM). The dependence of the resonant condition on the layer thicknesses and refractive index of the layers in the cavity is investigated in detail. The investigations reveal that the resonant condition for the MC is related to the optical interference between the light reflected from the interface between the layers in MC and the light reflected from the MC mirrors. In addition, the resonant wavelength of the cavity is modified by the interface reflection in the cavity. The results presented in this paper help to accurately control the resonant wavelength of the MC and to contribute to accurate design and fabrication of MC-based devices.
