Photoaligning and Photopatterning — A New Challenge in Liquid Crystal Photonics
Photoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells.

Putting the Photon into Photonics
Realising the disruptive applications offered by quantum photonics requires efficient production, processing, and detection of single photons. Here we review significant recent progress in efficient photon generation and processing-using quantum-dot systems-and discuss attractive near-term applications.

Photodetectors made using perovskite single crystals in combination with free‐standing cholesteric liquid crystal (CLC) polymer films exhibit photocurrent dissymmetry factors up to 1.95 for 520 nm circularly polarized light (CPL) excitation. The CPL spectral response of the photodetector is tunable over a broad range of wavelengths by tuning the ...

Experimental demonstration of the robust end state in a split-ring-resonator chain
One of the fascinating topological phenomena is the end state in one dimensional system. In this work, the topological photonics in the dimer chains composed by the split ring resonators are revealed based on the Su-Schrieffer-Heeger model.

Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3
Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...

HIGH ENERGY PHOTON-PHOTON AND ELECTRON-PHOTON COLLISIONS [PDF]
The advent of a next linear e±e- collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ*γ*→X in the region dominated by BFKL hard Pomeron exchange and report the ...

Photon-aided and photon-inhibited tunneling of photons [PDF]
In light of the interest in the transport of single photons in arrays of waveguides, fiber couplers, photonic crystals, etc., we consider the quantum mechanical process of the tunneling of photons through evanescently or otherwise coupled structures.

All‐Cellulose‐Based Photonic Glitters
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...
