In-fiber second-harmonic generation with embedded two-dimensional materials
Gia Quyet Ngo, Emad Najafidehaghani, Ziyang Gan +10
Silica-based optical fibers are a workhorse of nonlinear optics. They have been used to demonstrate nonlinear phenomena such as solitons and self-phase modulation. Since the introd…
Sensitive single-photon test of extended quantum theory with 2D hexagonal boron nitride
Tobias Vogl, Heiko Knopf, Maximilian Weissflog +2
Quantum theory is the foundation of modern physics. Some of its basic principles, such as Born's rule, however, are based on postulates which require experimental testing. Any devi…
Spatial coherence of room-temperature monolayer WSe exciton-polaritons in a trap
Hangyong Shan, Lukas Lackner, Bo Han +16
The emergence of spatial and temporal coherence of light emitted from solid-state systems is a fundamental phenomenon, rooting in a plethora of microscopic processes. It is intrins…
Fully tunable exciton-polaritons emerging from WS monolayer excitons in an optical lattice at room temperature
Lukas Lackner, Marco Dusel, Oleg A. Egorov +7
Engineering non-linear hybrid light-matter states in tailored optical lattices is a central research strategy for the simulation of complex Hamiltonians. Excitons in atomically thi…
Demonstration of a polariton step potential by local variation of light-matter coupling in a van-der-Waals heterostructure
C. Rupprecht, M. Klaas, H. Knopf +8
The large oscillator strength of excitons in transition metal dichalcogenide layers facilitates the formation of exciton-polariton resonances for monolayers and van-der-Waals heter…
Manipulation of room-temperature Valley-Coherent Exciton-Polaritons in atomically thin crystals by real and artificial magnetic fields
Christoph Rupprecht, Evgeny Sedov, Martin Klaas +11
Strong spin-orbit coupling and inversion symmetry breaking in transition metal dichalcogenide monolayers yield the intriguing effects of valley-dependent optical selection rules. A…
