Quantum Optics and Photonics---from fundamental quantum physics to real-world applications
The research carried out at IQE covers a broad spectrum in photonics and quantum optics. In its large trends, our research aims at pushing new concepts in quantum mechanics and electromagnetics and their applications in quantum systems, new devices, and optical sources. Specifically, making use of nano-fabricated structured semiconductors, we develop new optical sources in the mid-infrared and Terahertz spectral regions. Exploting the interaction between atoms and light, we investigate quantum phenomena in ultracold bosonic and fermionic gases. In mesoscopic physics, we study quantum correlations between individual photons that are generated by low-dimensional solid-state emitters. Within ultrafast physics, the frontiers in ultrafast science and technology are explored and pushed ahead: novel ultrafast lasers and measurement techniques from the infrared to the X-ray with pulse durations from femto-to attoseconds are developed. The activities at IQE are closely linked to the FIRST Laboratory for nano-fabrication and the center for quantum systems for information technology (QSIT).
