About this course

Skip About this course

Optomechanics is the study of the interaction between light and mechanical systems which can result in the manipulation of the state of both light and the mechanics. The nature of this interaction gives rise to a wide range of applications in both fundamental physics and technological advancements.

In this course, you will learn the concepts and tools required for conducting research in the field of cavity optomechanics. The key topics include the theoretical basis for studying both mechanical and optical resonators, the new physics emerging from their interaction, and the various tools and techniques used in designing a cavity optomechanical experiment.

The course is taught by a network of experts in the field comprising 14 partners from 12 renowned universities and 2 leading industries located in Austria, Belgium, Denmark, Finland, France, Germany, Italy, Netherlands, Switzerland.
