Rate My Professor Georg Rademacher

Rademacher's research focuses on advancing high-capacity optical transmission systems through spatial division multiplexing (SDM), MIMO equalization techniques, few-mode and multi-core fibers, nonlinear compensation in intensity-modulated direct-detection (IM/DD) links, and mode-group coupling mitigation. His contributions have enabled record-breaking data rates, crucial for supporting AI applications, data centers, and widespread digitalization. In 2025, he received the Johann Philipp Reis Prize from the VDE's Information Technology Society for his pioneering work on innovative glass fibers that achieve extremely high data rates using SDM methods. Rademacher leads DFG-funded projects, such as optical transmission testbeds for spatial multiplexing techniques and involvement in the Graduate Research School GRK 2642 on photonic quantum technologies. Notable publications include 'Space-division multiplexing for optical fiber communications' (Optica, 2021), 'Peta-bit-per-second optical communications system using a standard cladding diameter 15-mode fiber' (Nature Communications, 2021), '10.66 peta-bit/s transmission over a 38-core-three-mode fiber' (Optical Fiber Communication Conference, 2020), 'Wavelength division multiplexing of continuous variable quantum key distribution and 18.3 Tbit/s data channels' (Communications Physics, 2019), and 'Long-haul transmission over few-mode fibers with space-division multiplexing' (Journal of Lightwave Technology, 2018). His work demonstrates substantial influence in optical communications, with highly cited papers shaping future photonic network architectures.
