The investigation on Eu3+ high-doped PMMA planar optical waveguide by using scanning near-field optical microscopy

In this article, single- and multi-mode polymer optical waveguides doped with 2.5 wt% Eu(DBM)(3)Phen are prepared and measured by using scanning near-field optical microscopy and in-line method. The mode structure, near-field topography and near-field fluorescence are obtained, respectively. This may have potential applications in the study of polymer waveguide laser and amplifier.
