Abstract

Momentum transfer from light to particles was theorized in the XVII century byJohanes Kepler and experimentally demonstrated for the first time by Lebedev and, independently, by Nichols and Hull only in 1901. In optical cavities, as shown by V. Braginsky, this interaction may result in many interesting phenomena. In 2005 Tal Carmon demonstrated some of these effects in microfabricated cavities. In this thesis the results of studies on silicon nitride double-disk optomechanical microcavities are presented. Among these results are the theoretical demonstration that it is possible to drive such devices in the resolved side-band regime, exciting higher order mechanical modes, thermal noise measurements and optimization of the fabrication process, yielding cavities with mechanical quality factors close to 10000, in vacuum and at room temperature (AU)
