Modeling of Surface-Emitting Terahertz Quantum Cascade Laser Based on Difference Frequency Generation

A Hamadou, Jean-Luc Thobel

In this paper, we propose a simple method to calculate the THz field and THz power generated via intracavity difference frequency generation in a dual-wavelength mid-infrared quantum cascade laser. The approach is based on using a surface emission scheme in the nonlinear waveguide. The results show…

Quantum Coherent Transport of 1D ballistic states in second order topological insulator Bi$_4$Br$_4$

J. Lefeuvre, M. Kobayashi, G. Patriarche, Nathaniel Findling, D. Troadec, M Ferrier, S. Gueron, H. Bouchiat, T. Sasagawa, R. Deblock

We investigate quantum transport in micrometer-sized single crystals of Bi$_4$Br$_4$, a material predicted to be a second-order topological insulator. 1D topological states with long phase coherence times are revealed via the modulation of quantum interferences with magnetic field and gate voltage…
