Direct Wafer Bonding of Crystal-Ion-Sliced GaP Thin Films for Photonic Applications
Hossein Esfandiar, Emanuel Glück, Fabian Ganss +11
Gallium phosphide (GaP) is a promising material platform for integrated photonics because of its high refractive index, broad optical transparency, and strong second-order nonlinea…
Charge Tunable Optical Nonlinearity of Moiré Exciton-Polaritons
Zhijie Li, Kok Wee Song, Jens-Christian Drawer +16
Transition metal dichalcogenides represent a versatile platform to study strong light-matter interactions based on excitons and electrons in ordered lattices. Twist-engineering of…
Strong coupling regimes of an organic exciton mirror in a microcavity
Christoph Bennenhei, Lukas Lackner, Moritz Gittinger +7
The coherent, periodic energy transfer between light- and matter excitations characterizes the strong coupling regime of cavity exciton-polaritons, resulting, in the simplest case,…
Demonstration of a Monolithic and Fully Telecom-Fiber-Compatible Tunable Source of Polarization Entangled Photon Pairs Based on a van der Waals Material
Benjamin Laudert, Fatemeh Abtahi, Duk Choi +2
We present a tunable, single-mode-optical-fiber-based source of polarization entangled photon pairs for the near-infrared telecommunication band that is deployable in standard infr…
Sparse Spectral Imaging for Thickness Mapping of 3R-MoS on PDMS
Benjamin Laudert, Fatemeh Abtahi, Sarka Vavreckova +2
We present a non-destructive, spatially resolved thickness characterization method for rhombohedral (3R) molybdenum disulfide (MoS) on polydimethylsiloxane (PDMS) substrates. U…
Beyond Bragg-Mirrors for Gravitational Wave Telescopes: A Fabrication Tolerant Hybrid Metasurface-Bragg Mirror Design
Christian Kranhold, Mika Gaedtke, Markus Walther +3
Coating thermal noise in high-reflectivity test-mass mirrors is a major limitation for future gravitational-wave detectors, especially in the 10--300 Hz band. ET-Pathfinder therefo…
