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…
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…
An antipodal Vivaldi antenna for improved far-field properties and polarization manipulation of broadband terahertz quantum cascade lasers
Urban Senica, Elena Mavrona, Tudor Olariu +5
We present an antipodal Vivaldi antenna for broadband double metal waveguide terahertz quantum cascade lasers and frequency combs. Its exponentially curved flare profile results in…
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…
