Mattias Rasmussen

Mattias Rasmussen is a Researcher at the Department of Electrical and Photonics Engineering, Technical University of Denmark (DTU), affiliated with the Center for Nanophotonics (NanoPhoton).

Education:

• PhD in Photonics, Technical University of Denmark, 2024

Research Interests: Terahertz Spectroscopy, 2D Materials, Graphene, Nonlinear Optics, Photonics, Silicon Nitride, and THz-TDS. His work explores nonlinear conductivity in graphene, dispersion of nonlinearities in dielectrics, and advanced THz waveform detection.

Publications (14): His recent studies include Scanning-Free Solid-State Biased THz Waveform Detection (2025), Measurement of χ(3) Dispersion in SiO₂/SiN (2024), and THz Air Photonics (2024), alongside key contributions to two-color air-plasma THz beam profiling and broadband nonlinear THz spectroscopy.

Projects: Completed his PhD project Nonlinear Terahertz Transport Dynamics of 2D Materials in the Ballistic Regime (2020–2024) under supervisors B. Zhou and P.U. Jepsen.
