In light-matter strong coupling regime, we observe long-range photodetection response at room temperature mediated by organic exciton-polaritons, which results from strong interactions between organic excitons and low-loss Bloch surface wave (BSW) modes.
We propose a quantum circuit that emulates a delayed-choice quantum eraser via bipartite entanglement with the extension that the degree of entanglement between the two paired quantons is adjustable. This provides a b...

The study introduces a 3D-printed lens assembly that has been rotated and equipped with an ultrawideband (UWB) antenna, designed specifically for beam-steering applications. The primary objective is to achieve beam steering by integrating the rotating 3D-printed lens assembly with a hemispherical lens and UWB antenna. The UWB antenna is constructed on an FR-4 substrate, while the hemispherical lens and the rotating 3D-printed lens assembly are composed of Acrylonitrile Butadiene Styrene (ABS). To allow the hemispherical lens to rotate to a certain angle, a collection of 3D-printed lenses that can be rotated was created. These lenses were marked with five predetermined angles: 300 degrees, 330 degrees, 0 degrees, 30 degrees, and 60 degrees. Both the modeling and experimental findings demonstrate that the UWB antenna with the 3D-printed rotatable hemispherical lens assembly is unable to guide the beam at a low frequency of 3.1 GHz. Nevertheless, at frequencies of 7.0 GHz and 10.6 GHz for intermediate and high frequencies, respectively, the beam can be directed based on the rotation of the hemispherical lens.

In this work, we report the spontaneous formation of superlattice structures in nominal InGaN films grown by plasma-assisted molecular beam epitaxy. A 700-nm-thick self-assembled In0.2Ga0.8N/GaN superlattice with excellent structural quality was achieved. Strain was studied as a possible driving force for the formation of self-assembled superlattice (SASL) structure by growth of InGaN on ZnO substrate using similar growth conditions. The SASL structures were optically characterized using photoluminescence spectroscopy. Structural characterization was conducted via transmission electron microscopy and atom probe tomography. High-resolution x-ray diffraction (XRD) and XRD reciprocal space map were utilized to determine the average composition and the degree of relaxation of InGaN films. We propose that the vertical phase separation observed in the SASL structure is caused by high-temperature growth and intensified by strain. This work provides a method for engineering strain and growth of thick InGaN films for a variety of applications including solar cells and photodetectors.
