Prof. Dr. Stephan Reitzenstein is Director of the Institute of Physics and Astronomy at TU Berlin, and chairperson of the Berlin School of Optical Sciences and Quantum Technologies (BOS.QT).
This talk presents recent advances from Prof. Dr. Reitzenstein's group in developing quantum-dot–based quantum light sources for quantum communication networks and integrated quantum nanophotonic platforms. Using deterministic fabrication methods, they achieve precise emitter–cavity coupling and high-performance single-photon generation. In parallel, they explore novel nanophotonic structures based on 2D TMDC heterostructures to realize ultrathin, tunable, and highly efficient photonic functionalities.
Their research also includes the design and realization of vertically emitting microlasers that serve as compact, low-threshold coherent light sources. Among these, next-generation VCSEL architectures are being investigated for their potential in neuromorphic computing, enabled by their fast dynamics and energy-efficient operation.
Together, these developments outline a path toward scalable, multifunctional photonic systems for future quantum and neuromorphic technologies.
