Surface Plasmon Polariton Waveguides in Nonlinear Optical Polymer

摘要

Nonlinear optical materials are used as substrates for electrically addressable surface plasmon polariton waveguides. Materials preparation including the mixing of chromophores and polymers and their coating and poling is described. The film quality is studied by various techniques including atomic force microscopy. Techniques for fabricating surface plasmonic guides in the nonlinear polymer films are detailed. Measurements of surface plasmon polariton propagation in the resulting structures are presented. The measured field structures of the plasmonic guides are displayed and compared with fields calculated with theoretical models.
