Paper Abstract

In this paper we present two-photon excitation of MDR within a doped polymer micro-sphere. Two-photon technology can be used to induce localized physical change in materials. Due to the highly localized nature of two-photon excitation, the induction of MDR into a micro-cavity can be tightly controlled. A clear and easy separation of excitation and resonant wavelengths is inherent under two-photon excitation. It is shown that the adjacent MDR peaks have orthogonal polarized components, and can be controlled by the position of an excitation spot in a micro-sphere. It is also demonstrated that the micro-cavity MDR peaks have a good agreement with Mie scattering theory.
