Intrinsically chiral exciton polaritons in an atomically-thin semiconductor
Matthias J. Wurdack, Ivan Iorsh, Sarka Vavreckova +15
Photonic bound states in the continuum (BICs) have emerged as a versatile tool for enhancing light-matter interactions by strongly confining light fields. Chiral BICs are photonic…
Fabrication of low-loss lithium niobate on insulator waveguides on the wafer scale
Mohammadreza Younesi, Thomas Kasebier, Ilia Elmanov +8
We report on the wafer scale fabrication of single mode low-loss lithium niobate on insulator waveguides utilizing a chemically amplified resist and an optimized dry etching method…
Optical characterization of size- and substrate-dependent performance of ultraviolet hybrid plasmonic nanowire lasers
Francesco Vitale, Stephen A. Church, Daniel Repp +10
Nanowire-based plasmonic lasers are now established as nano-sources of coherent radiation, appearing as suitable candidates for integration into next-generation nanophotonic circui…
Directionally Tunable Co- and Counter-Propagating Photon Pairs from a Nonlinear Metasurface
Maximilian A. Weissflog, Jinyong Ma, Jihua Zhang +6
Nonlinear metasurfaces have recently been established as a new platform for generating photon pairs via spontaneous parametric down-conversion. While for classical harmonic generat…
Entangled Photon-pair Generation in Nonlinear Thin-films
Elkin A. Santos, Maximilian A. Weissflog, Thomas Pertsch +2
We develop a fully vectorial and non-paraxial formalism to describe spontaneous parametric down-conversion in nonlinear thin films. The formalism is capable of treating slabs with…
Influence of resonant plasmonic nanoparticles on optically accessing the valley degree of freedom in 2D semiconductors
Tobias Bucher, Zlata Fedorova, Mostafa Abasifard +10
The valley degree of freedom is one of the most intriguing properties of atomically thin transition metal dichalcogenides. Together with the possibility to address this degree of f…
