Recommended as a 2nd year master course or PhD course. Prvious knowledge of basic solid-state physics is useful.


1. Semiconductor lasers: gain, resonators, waveguides, effects and properties. VCSELs, lasers in external cavity, DFB lasers. Nanostructured lasers and quantum cascade lasers. Semiconductor Optical Amplifiers.

2. Terahertz photonics: Auston switches, time-domain spectroscopy, THz applications and sources.

3. Mode-locking: theory and techniques (passive mode-locking, active, self-focusing). Frequency combs and their use in spectroscopy.

4. Non-linear devices: propagation equations, phase matching. Parametric amplification and parametric oscillators, electro-optical modulators.

5. Vacuum Rabi oscillations and Rabi splitting: excitonic and intersubband polaritons. Concept of ultra-strong coupling and non-adiabatic phenomena. Stimulated emission in a microcavity and lasing without threshold.

6. Devices for the detection of radiation: photodiodes, avalanche diodes, photoconductors, Quantum Well Infrared Photodetectors and THz "plasma wave" detectors.

7. Elements of quantum information and implementations in photonics: qubits, entanglement, CNOT gate, Bell inequality. Quantum teleportation and quantum cryptography experiments.

8. Elements of cavity QED: experiments and applications to quantum computation.

9. Atomic clocks and frequency combs


Educational goals
