摘要
In this paper, leakage radiation microscopy (LRM) was used to characterize the surface plasmon coupled emission (SPCE) and waveguide mode coupled emission (WMCE). Rhodamine (RhB) molecules doping PMMA films with different thicknesses were spin-coated onto silver films deposited on a glass substrate, which were used to generate both the SPCE and WMCE. A numerical simulation was carried out and was consistent with the experimental results, which verifies the feasibility of this method. When compared with a prism-based set-up, LRM has the advantages of getting the emitting angle without scanning and higher spatial resolution.
