Abstract

Optical microcavity is a high quality factor micro-cavity with a size of the resonant wavelength. By using of spontaneous emission modulation of organic gain medium, an organic microcavity laser can be achieved. In this paper, a metal Ag-dielectric DBR mirrors mixed organic micro-cavity structure was proposed in this paper. And the influences of center wavelength, growth sequence and the cycle number of DBR, and the thickness of Ag mirror and organic light-emitting layer on performance of Ag-DBR mixed organic micro-cavity were investigated by simulation. And then according to PL characteristics of Alq3:DCM(0.5wt%), an optimal metal Ag-DBR microcavity structure was designed, and based on theoretical calculation results, a corresponding microcavity devices (air/Ag/organic layer/DBR/glass) was fabricated. The experimental and theoretical simulation results are in good agreement. The results show that the calculation method of ours is of great guided significance on the fabrication of metal-DBR organic microcavity lasers.
