Description of Achievement and Assessment Methods

The examination consists of an oral examination of approximately 30 minutes at the end of the semester. The subject of the examination is a basic understanding of the concepts taught in the lecture, thus determining the achievement of the competencies presented in the section Study Goals. In case of a large number of participants, the oral exam can be replaced by a 60-minute written exam.

Prerequisites (recommended)

Bachelor of Electrical Engineering, Physics or equivalent. Basic knowledge of solid state physics, quantum mechanics and quantum optics are desirable.

Intended Learning Outcomes

Upon successful completion of the module, students will acquire knowledge of optomechanical systems in the quantum regime and will be able to evaluate developments in this field. In particular, an understanding of the following fundamental concepts will be obtained:
- parametric coupling of a mechanical resonator and an optical cavity and dynamical backaction.
- optomechanical ground state cooling
- applications of quantum optomechanics


The module consists of a lecture and accompanying exercises. The lecture deals with the fundamentals of cavity optomechanics with special focus on the quantum mechanical regime. It includes an overview of optomechanical systems, the theoretical description of radiation pressure-induced coupling and its effects, optomechanical cooling to the ground state, and modern applications of optomechanical systems in the quantum regime.

Teaching and Learning Methods

The lecture is taught on the blackboard and with projected slides. In addition, students will have ample opportunity for questions and discussion.
In the exercise groups, the learned content is deepened and supplemented by exercises. In addition, current scientific publications are regularly discussed.
