Electromagnetic field distribution and resonance modes in Tamm structure are analyzed based on transfer matrix method, and a hybrid aperture-Tamm structure is proposed to enhance the fluorescence signal and control the emission direction. The finite difference time domain (FDTD) method is used to simulate the far field emission of dipole source interacted with hybrid aperture-Tamm structure. It is proved that this structure can realize the vertical ejection of fluorescence and the fluorescence intensity increases by three orders of magnitude compared with the conventional Tamm structure. Influences of fluorescence emission wavelength, position of dipole source, the size and shape of aperture on radiation angle and intensity are systematically analyzed and compared. Simulation results can be used as a guide for the optical chip design with fluorescence enhanced directional radiation function.
