Mid-infrared quantum cascade laser frequency combs with a microstrip-like line waveguide geometry
Filippos Kapsalidis, Barbara Schneider, Matthew Singleton +4
In this work, a design for a mid-infrared quantum cascade laser (QCL) frequency comb source that enhances the high frequency response and the comb characteristics of the device is…
Non-Invasive Near-field Spectroscopy of Single Sub-Wavelength Complementary Resonators
Lucy L Hale, Janine Keller, Thomas Siday +7
Subwavelength metallic resonators provide a route to achieving strong light-matter coupling by means of tight confinement of resonant electromagnetic fields. Investigation of such…
Mid-infrared quantum cascade laser frequency combs based on multi-section waveguides
Ruijun Wang, Philipp Taschler, Filippos Kapsalidis +3
We present quantum cascade laser (QCL) frequency comb devices with engineered waveguides for managing the dispersion. The QCL waveguide consists of multiple sections with different…
Controlling and Phase-Locking a THz Quantum Cascade Laser Frequency Comb by Small Optical Frequency Tuning
L. Consolino, A. Campa, M. De Regis +7
Full phase control of THz emitting quantum cascade laser (QCL) combs has recently been demonstrated, opening new perspectives for even the most demanding applications. In this fram…
Monte Carlo Modeling of Terahertz Quantum Cascade Detectors
Johannes Popp, Michael Haider, Martin Franckié +2
We demonstrate an Ensemble Monte Carlo (EMC) modeling approach for robust and rigorous simulations of photovoltaic quantum cascade detectors (QCDs) in the mid-infrared (mid-IR) and…
Topological charge of finite-size photonic crystal modes
Zhixin Wang, Yong Liang, Mattias Beck +2
Topological charges are the winding numbers of polarization vectors around the vortex centers of far-field radiation. In this work, the topological charge of photonic crystal modes…
