Boosting self hybridized exciton polaritons with metal clad WS2 waveguides
Filip Majstorovic, Masoud Taleb, Victor DeManuel-Gonzalez +2
The formation of Fabry Perot and guided wave self hybridized exciton polaritons in two dimensional materials results in long range exciton energy transfer and strong exciton excito…
Meshfree versus grid-based Schrödinger solvers for modeling the interactions between free-electron wave packets and light
Mitja Funk, Sebastian Merk, Caroline Lasser +2
The interaction of free-electron wave packets with electromagnetic fields provides a powerful route toward coherent electron control, enabling the generation of energy combs, momen…
Stimulated interactions of low-energy free-electrons with light
Fatemeh Chahshouri, Sven Ebel, Mitja Funk +1
Free-electron interactions with light and matter have long served as a cornerstone for exploring the quantum and ultrafast dynamics of material excitation. In recent years, this pa…
Probing quantum-coherent dynamics with free electrons
H. B. Crispin, N. Talebi
Recent advances in time-resolved cathodoluminescence have enabled ultrafast studies of single emitters in quantum materials with femtosecond temporal resolution. Here, we develop a…
A Multi-Dimensional Cathodoluminescence Detector with 3D Printed Micro-Optics on a Fiber
Paul H. Bittorf, Filip Majstorovic, Pavel Ruchka +2
Cathodoluminescence, i.e. the radiation caused by the interaction of high-energy electron beams with matter, has gained a major interest in the analysis of minerals, semiconductors…
Phase-matched electron-photon interactions enabled by 3D-printed helical waveguides
Masoud Taleb, Mohsen Samadi, Nahid Talebi
The Smith-Purcell effect enables electromagnetic radiation across arbitrary spectral ranges by phase-matching the diffraction orders of an optical grating with the near-field of a…
