| 227-0653-00L | Electromagnetic Precision Measurements and Opto-Mechanics Does not take place this semester. | 4 credits | 2V + 1U | M. Frimmer | |
| Abstract | The measurement process is at the heart of both science and engineering. Electromagnetic fields have proven to be particularly powerful probes. This course provides the basic knowledge necessary to understand current state-of-the-art optomechanical measurement systems operating at the precision limits set by the laws of quantum mechanics. | ||||
| Objective | The goal of this coarse is to understand the fundamental limitations of measurement systems relying on electromagnetic fields. | ||||
| Content | The lecture starts with summarizing the relevant fundamentals of the treatment of noisy signals. Starting with the resolution limit of optical imaging systems, we familiarize ourselves with the concept of measurement imprecision in light-based measurement systems. We consider the process of photodetection and discuss the statistical fluctuations arising from the quantization of the electromagnetic fields into photons. We exemplify our insights at hand of concrete examples, such as homodyne and heterodyne photodetection. Furthermore, we focus on the process of measurement backaction, the inevitable result of the interaction of the probe with the system under investigation. The course emphasizes the connection between the taught concepts and current state-of-the-art research carried out in the field of optomechanics. | ||||

| 227-0663-00L | Nano-Optics  | 6 credits | 2V + 2U | M. Frimmer | |
| Abstract | Nano-Optics is the study of light-matter interaction at the sub-wavelength scale. It is an flourishing field of fundamental and applied research enabled by the rapid advance of nanotechnology. Nano-optics embraces topics such as plasmonics, optical antennas, optical trapping and manipulation, and high/super-resolution imaging and spectroscopy. | ||||
| Objective | Understanding concepts of light localization and light-matter interactions on the sub-wavelength scale. | ||||
| Content | We start with the angular spectrum representation of fields to understand the classical resolution limit. We continue with the theory of strongly focused light, the point spread function, and resolution criteria of conventional microscopy, before turning to super-resolution techniques, based on near- and far-fields. We introduce the local density of states and approaches to control spontaneous emission rates in inhomogeneous environments, including optical antennas. Finally, we touch upon optical forces and their applications in optical tweezers. | ||||
| Prerequisites / Notice | - Electromagnetic fields and waves (or equivalent) - Physics I+II | ||||
| 227-1831-10L | Case Studies: Applications of Quantum Technology  Only for Quantum Engineering MSc | 3 credits | 6G | L. Novotny, M. Frimmer, G. Raino | |
| Abstract | In this course students will be exposed to different topics of quantum engineering and develop ideas for possible projects. Based on presentations by ETH labs participating in the MSc QE program and with the assistance of a mentor students will work in groups to develop concrete plans for a quantum experiment. | ||||
| Objective | Acquire a broad overview of quantum engineering activities at ETH and develop own ideas about future quantum engineering projects. | ||||
