| 402-0466-15L | Quantum Optics with Photonic Crystals, Plasmonics and Metamaterials | 6 KP | 2V + 1U | G. Scalari | |
| Kurzbeschreibung | In this lecture, we would like to review new developments in the emerging topic of quantum optics in very strongly confined structures, with an emphasis on sources and photon statistics as well as the coupling between optical and mechanical degrees of freedom. | ||||
| Lernziel | Integration and miniaturisation have strongly characterised fundamental research and industrial applications in the last decades, both for photonics and electronics. The objective of this lecture is to provide insight into the most recent solid-state implementations of strong light-matter interaction, from micro and nano cavities to nano lasers and quantum optics. The content of the lecture focuses on the achievement of extremely subwavelength radiation confinement in electronic and optical resonators. Such resonant structures are then functionalized by integrating active elements to achieve devices with extremely reduced dimensions and exceptional performances. Plasmonic lasers, Purcell emitters are discussed as well as ultrastrong light matter coupling and opto-mechanical systems. | ||||

| Inhalt | Since their invention, the optical frequency combs have shown to be a key technological tool with applications in a variety of fields ranging from astronomy, metrology, spectroscopy and telecommunications. Concomitant with this expansion of the application domains, the range of technologies that have been used to generate optical frequency combs has recently widened to include, beyond the solid-state and fiber mode-locked lasers, optical parametric oscillators, microresonators and quantum cascade lasers. In this lecture, the goal is to review the physics behind mode-locking in these various devices, as well as discuss the most important novelties and applications of the newly developed sources. Chapt 1: Fundamentals of optical frequency comb generation - Physics of mode-locking: time domain picture Propagation and stability of a pulse, soliton formation - Dispersion compensation Solid-state and fiber mode-locked laser Chapt 2: Direct generation Microresonator combs: Lugiato-Lefever equation, solitons Quantum cascade laser: Frequency domain picture of the mode-locking Mid-infrared and terahertz QCL combs Chapt 3: Non-linear optics DFG, OPOs Chapt 4: Comb diagnostics and noise Jitter, linewidth Chapt 5: Self-referenced combs and their applications Chapt 6: Dual combs and their applications to spectroscopy | ||||
