description: Within the quick nano-fabrication techniques evolution and the increasing needs in low space and energy opto-electronic functions on-chip integration, studies and control of electromagnetic resonances of sub-micrometric objects are crucial issues. One aim of this work was then to improve our knowledge of the light-matter interaction. To this end, optical near-field experiments and complementary numerical development of models have been performed to study electromagnetic resonances due to light-matter interaction in sub-micrometric resonators. As an introduction, the first part of the manuscript presents the main phenomena involved in near-field optical microscopy and the used SNOM operation. The second part is dedicated to nearfield tip/Fabry-Perot micro-resonator interaction in the non-linear regime. In this part, we first present the study of high-Q/small volume Silicon nano-cavity non-linearities, showing possible bistable operation at very low incident power. We then demonstrate the cavity stability modulation obtain with the near-field tip. In the third part of the manuscript, we consider thin metallic film resonances. As a beginning, we realize an exhaustive study of the film eigenmodes and then discuss the resonant optical excitation of the film as well as precise determination of Brewster angle. These theoretical studies have been extended experimentally with the optical near-field determination of the resonant modes of semi-infinite thin films. For the different studies, experimental measures have been systematically associated with theoretical analyses and numerical developments of models, which have then been confirmed or discussed in light of the experimental results.
