Martin Arentoft Jacobsen

Martin Arentoft Jacobsen serves as an Assistant Professor in the Department of Electrical and Photonics Engineering at the Technical University of Denmark (DTU), specializing in quantum light source development. His research centers on semiconductor quantum dot systems for practical single-photon generation, addressing critical challenges in quantum technology implementation.

His educational foundation includes a PhD in Photonics from DTU (2020-2023), where he completed the dissertation "Design and Simulations of Quantum Light Sources" under supervision of Prof. Niels Gregersen. This doctoral work established his expertise in computational modeling of quantum photonic devices.

Dr. Jacobsen's research program strategically targets quantum photonics bottlenecks through three interconnected thrusts: (1) Engineering dielectric nanostructures like rings and nanoposts to maximize collection efficiency and β factors, (2) Developing deterministic fabrication protocols for quantum dot positioning, and (3) Implementing advanced simulation frameworks that bridge quantum electrodynamics with nanofabrication constraints. His approach combines rigorous theoretical modeling with experimental validation to overcome background emission and radiation mode losses.

Analysis of his 2022-2024 publications reveals a consistent trajectory toward practical quantum light sources. Key advancements include dielectric ring architectures achieving near-unity collection efficiency, nanopost designs transcending single-mode limitations, and fabrication accuracy assessments for quantum dot devices. These contributions establish critical pathways for scalable quantum photonic integrated circuits.

As an emerging independent researcher, Dr. Jacobsen has not yet supervised graduate students but leads the Quantum Light Sources initiative within DTU's Department of Electrical and Photonics Engineering. His current projects build upon DTU's institutional research infrastructure, with future work expected to secure competitive quantum technology grants.

He maintains active collaborations with CEA-LETI (France) and international quantum photonics leaders including Prof. Jean-Michel Gérard. The research group focuses on transitioning quantum dot single-photon sources from laboratory demonstrations to manufacturable components for quantum communication networks.
