DBR-Ag Micro-Cavity Organic Solid-State Lasers

Abstract:

A DBR-Ag mixed organic micro-cavity structure solid-state laser was proposed in this paper. 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. According to PL characteristics of Alq3:DCM (0.5wt%), an optimal metal Ag-DBR micro-cavity structure was designed, and based on theoretical calculation results, a corresponding micro-cavity devices (glass/DBR/organic layer/Ag mirror) was fabricated. The theoretical simulation and experimental results are in good agreement.
