Single-Course English 5 ECTS

Optics and photonics

Overall Course Objectives

The course provides a broad introduction to both classical and modern optics and photonics. The aim is that the students obtain a physical understanding of what light is, how it interacts with matter, and how light is used in measurement techniques and information technology.

Learning Objectives

  • Identify whether a ray optics, a scalar wave optics, an electromagnetic wave optics, or a photon optics description is required in a given situation
  • Derive the wave equation from Maxwell’s equations in a medium and understand the different solutions and their characteristic properties
  • Describe the superposition principle and apply it to electromagnetic waves
  • Describe the concept of interference and calculate the properties of different interferometric systems
  • Explain Fourier analysis of optical waves
  • Explain the concept of polarization, describe several polarization states of light and how they can be generated and transformed
  • Describe and calculate the propagation of light in simple optical waveguides in terms of modes, dispersion relation and effective index
  • Explain the concepts of Fraunhofer and Fresnel diffraction and calculate the diffraction patterns of different apertures
  • Derive the Fresnel equations and describe how light is transferred at an interface of two materials, and through multilayer films
  • Describe the interaction between light and matter and explain the basic principles of a laser
  • Apply and recognize professional terminology in English

Course Content

The following concepts and phenomena, and some of their most important applications: Light rays, Maxwell wave equations, vector fields and polarization properties, wave diffraction, wave interference and superposition of waves, Fresnel relations, periodic media and multilayers, waveguide optics, optical resonators, light-matter interactions, laser amplification and lasers
