Regular modules

These modules are offered for „Physics of Light“ on a regular basis. Please note: Each module usually corresponds to a single course with the same title. In a few cases, a module is linked to two courses which will then have different titles.

Summer term

Modern Optics 2: Non-linear optics

 

Prof. Dr. Joly, Dr. Fattahi, 5 ECTS

  • Linear properties of materials.
  • Origin of the nonlinear susceptibility.
  • Importance of phase-matching.
  • Second harmonic generation, derivation of the set of coupled equations.
  • Importance of the initial phase and case of seeding second harmonic generation. Use of birefringence to achieve phase-matching.
  • Electro-optic effects.
  • Nonlinear process in relation to third order nonlinearity.
  • Modulation instability, soliton formation, perturbations of soliton, and supercontinuum generation.
  • Application: nonlinear optics in photonic crystal fibers.

Quantum Optics

 

Prof. Dr. Chekhova, 5 ECTS

  • Basic concepts of statistical optics
  • Spatial and temporal coherence. Coherent modes, photon number per mode
  • Intensity fluctuations and Hanbury Brown and Twiss experiment
  • Interaction between atom and light (semiclassical description)
  • Quantization of the electromagnetic field
  • Quantum operators and quantum states
  • Heisenberg and Schrödinger pictures
  • Polarization in quantum optics
  • Nonlinear optical effects for producing nonclassical light
  • Parametric down-conversion and four-wave mixing, biphotons, squeezed light
  • Single-photon states and single-photon emitters
  • Entanglement and Bell’s inequality violation

Advanced Laser

 

Prof. Dr. Joly, 5 ECTS

This module naturally follows the “Basics of Lasers” module and aims at deepen the knowledge on a few specific aspects of lasers. In particular we will study the Z-cavity of one of the most popular laser system: the Titanium: sapphire laser. The purpose here is to show why simpler cavity is not possible. It requires understanding properly the concept of stability of laser cavity and introduces the problem of astigmatism. In a second stage we see how dispersion effects can hamper the properties of a mode-locked laser system and see how to circumvent this. We then study the different method used to characterize ultrashort laser pulse. This starts from basics concepts of autocorrelation but review more advanced techniques allowing to retrieve fully the amplitude and phase of a laser pulse. Towards the end of the lecture several topics are possible and it will be chosen together with the students. This can be for instance (i) the polarization and the Jones’ formalism (ii) the Maxwell-Bloch equations (iii) the origin of spontaneous emission. Finally in order to broaden the contents of the lecture the students are asked to prepare one half-an-hour presentation of the topics of their choice. The topics are discussed during the first two sessions of the lecture and must focus on a physical aspect of laser.

Winter term

Advanced Course in Experimental Physics

 

Prof. Dr. von Zanthier, 10 ECTS

The module discusses light-matter interaction in different systems as well as the quantum nature of light. Emphasis is put onto the laser. Starting from the theory of optical resonators and Gaussian beams we review the generation of laser light on a microscopic level (Maxwell-Bloch equations) and examine its principal characteristics. Various applications of laser light in quantum optics, laser spectroscopy, laser cooling and trapping of atoms and in non-linear optics are investigated. In addition we review various quantum optical phenomena like photon statistics, photon bunching/anti-bunching, multi-photon interferences, intensity interferometers and resonance fluorescence.

Quantum Computing

 

Prof. Dr. Hartmann, 5 ECTS

The course provides an introduction to quantum computing. The development of quantum hardware has progressed substantially in recent years and has now reached a level of maturity where first industrial applications are being explored. This course will introduce the fundamental ingredients of quantum algorithms, quantum bits and quantum gates, the most important hardware implementations and in particular algorithms that can run on near term hardware implementations of so called Noisy Intermediate Scale Quantum (NISQ) devices. The course will be completed with introductions to the basic concepts of error correction, which is needed in the next stage of development to fully exploit the potential of this emerging computing technology. Prerequisites: the main concepts of quantum theory, including quantum states, the Schrödinger equation, unitary evolution and measurements.

Theoretical Methods for Optical Properties of Solids

 

Dr. Roland Gillen, 5 ECTS

The lecture series will discuss modern (and less modern) theoretical methods for the simulation of optical spectra of crystalline materials. A focus will lie on the proper description of excitonic and trionic contributions, which are important in one- and two-dimensional materials. Examples in the form of calculations and paper reviews will be integrated into the lectures.

Selected topics are:

  • Excitons in solid, particularly one- and two-dimensional materials

  • Effective mass-based approaches

  • Tight-binding

  • Modern ab initio methods, such as density-matrix based approaches and the excitonic Bethe-Salpeter Equation
