Abstract
The objective of the project is to study the propagation of electromagnetic waves in photonic crystal structures, which are systems with periodically modulated dielectric constants. Similar to the electronic case, the optical dispersion relation for the structure can exhibit regions forbidden for the propagation of light within the crystal, also known as photonic bandgaps. Through engineered defects in the crystal's periodicity, it is possible to create waveguides and optical cavities. Light confined within the optical cavity can also interact with its mechanical structure through radiation pressure, in what is called optomechanical interaction. A theoretical and experimental study of the cavities and optomechanical interaction is carried out based on analytical analyses and numerical simulations (AU)
