Abstract
We numerically modeled and experimentally investigated a photonic crystal (PhC) heterostructure cavity with a three-dimensionally (3D) ordered colloidal PhC made from rhodamine-B dye-doped polymer colloids sandwiched between two identical dielectric multilayer stacks, for its influence on dye emission. In this cavity, we utilized the effect of overlap of the defect cavity mode of a multilayer stack with the band edge of 3D PhC to achieve enhancement and spectral narrowing in dye emission. The other defect modes, which do not overlap with the band edge, do not show this effect.
