Ultrafast Non-Hermitian Skin Effect
Barbara Schneider, Alexander Dikopoltsev, Markus Bestler +5
Topological phases of matter commonly feature protected states at their boundaries. Transferring this protection to time-metamaterials is extremely challenging, as it requires the…
Combs, fast and slow: non-adiabatic mean field theory of active cavities
David Burghoff
Integrated frequency combs based on active cavities are of interest for a wide range of applications. An elegant description of these cavities is based on mean-field theory, which…
Fundamental scaling limits and bandwidth shaping of frequency-modulated combs
Mithun Roy, Zhenyang Xiao, Sadhvikas Addamane +1
Frequency-modulated (FM) combs based on active cavities like quantum cascade lasers have recently emerged as promising light sources in many spectral regions. Unlike passive modelo…
Frequency combs in optically-injected terahertz ring quantum cascade lasers
Md Istiak Khan, Zhenyang Xiao, Sadhvikas J. Addamane +1
Quantum cascade lasers (QCLs) have emerged as promising candidates for generating chip-scale frequency combs in mid-infrared and terahertz wavelengths. In this work, we demonstrate…
Optical-pump terahertz-probe spectroscopy of the topological crystalline insulator Pb1-xSnxSe through the topological phase transition
Zhenyang Xiao, Jiashu Wang, Xinyu Liu +2
Topological crystalline insulators -- topological insulators whose properties are guaranteed by crystalline symmetry -- can potentially provide a promising platform for terahertz o…
High-Q longwave infrared microresonators based on a non-epitaxial germanium platform
Dingding Ren, Chao Dong, David Burghoff
The longwave infrared (LWIR) region of the spectrum spans 8 to 14 μm and enables high-performance sensing and imaging for detection, ranging, and monitoring. Chip-scale integrated…
