Power distribution in the luminescent waveguide

This paper describes how to calculate the power distribution emitted by luminescent particles which are mixed in the film of the waveguide, i.e., the percentage of the power transported by each guided mode, emitted to the cladding and the substrate. For our sample, they are ~20%, 25%, and 55% separately. Some calculated results have been proved: the powers of the TE and TM modes of the luminescent waveguide in the same order are almost the same; the order of the film mode is lower; its power is larger.
