Emitter and absorber assembly for multiple self-dual operation and directional transparency
P. A. Kalozoumis, C. V. Morfonios, G. Kodaxis +2
A recursive scheme for the design of scatterers acting simultaneously as emitters and absorbers, such as lasers and coherent perfect absorbers in optics, at multiple prescribed fre…
High-energy mid-infrared sub-cycle pulse synthesis from a parametric amplifier
Houkun Liang, Peter Krogen, Zhou Wang +8
High-energy, carrier-envelope phase (CEP)-stable, sub-cycle, mid-infrared (mid-IR) pulses can provide unique opportunities of exploring phase-sensitive strong-field light-matter in…
Imaging electron dynamics with time- and angle-resolved photoelectron spectroscopy
Daria Popova-Gorelova, Jochen Küpper, Robin Santra
We theoretically study how time- and angle-resolved photoemission spectroscopy can be applied for imaging coherent electron dynamics in molecules. We consider a process in which a…
Thermal x-ray diffraction and near-field phase contrast imaging
Zheng Li, Anton Classen, Tao Peng +4
Using higher-order coherence of thermal light sources, the resolution power of standard x-ray imaging techniques can be enhanced. In this work, we applied the higher-order measurem…
Cascaded Parametric Amplification for Highly Efficient Terahertz Generation
Koustuban Ravi, Michael Hemmer, Giovanni Cirmi +4
A highly efficient, practical approach to high-energy terahertz (THz) generation based on spectrally cascaded optical parametric amplification (THz-COPA) is introduced. The THz wav…
symmetry breaking in waveguide arrays with competing loss/gain pairs
P. A. Kalozoumis, C. V. Morfonios, F. K. Diakonos +1
We consider a periodic waveguide array whose unit cell consists of a -symmetric quadrimer with two competing loss/gain parameter pairs which lead to qualitatively dif…
