Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides
Advanced Optical Materials, EarlyView.Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.

Advanced Photonics Research, EarlyView.The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides
Advanced Photonics Research, EarlyView.Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

Advanced Photonics Research, EarlyView.Optical simulations of composite plasmonic split‐ring resonators show that a magnetic response can be obtained at wavelengths near the visible regime. The response is further increased by extending the geometry and enabling a Fano resonance through the coupling of magnetic dipoles.
