Article Abstract
We present polarization-dependent optical transmission properties of a completely symmetric silicon-on-insulator (SOI) microphotonic material system. In contrast to typical SOI based photonic materials, here an insulator-on-silicon-on-insulator (IOSOI) material system has been fabricated. This symmetric structure exhibits average losses between 1510 and 1630 nm of around 0.5 dB/mm for TE and 0.3 dB/mm for TM-polarization. The good transmission for TM-polarization can be explained by the thick insulting cladding layer of 3 microm thickness. Moreover, group index dispersion diagrams are presented and discussed for both polarizations.

The photonic flat band, defined by minimal dispersion and near-zero group velocity, has facilitated significant advances in optical technologies. The practical applications of flat bands, such as enhanced light-matter interactions, require efficient coupling to far-field radiation. However, achieving controlled coupling between flat bands and their corresponding localized modes with far-field radiation remains challenging and elusive.

We develop an ab initio framework that captures the impact of electron-electron and electron-hole interactions on phonon properties. This enables the inclusion of excitonic effects in the optical phonon dispersions and lifetimes of graphene, both near the center (Γ) and at the border (K) of the Brillouin zone, at phonon-momenta relevant for Raman scattering and for the onset of the intrinsic electrical resistivity. Near K, we find a phonon redshift of ∼150 cm^{-1} and a 10× enhancement of the group velocity, together with a 5× increase in linewidths due to a 26× increase of the electron-phonon matrix elements.

Organic molecular glasses are attractive matrices to disperse active ingredients in pharmaceuticals or electronic devices. Typically, they i) have lower glass transition temperatures than inorganic or polymeric glasses, making them easier to process, and ii) are less prone to phase segregation from other organic active materials. However, there is a dearth of functional groups that are known to induce glass formation in preference to crystallization.

Tungsten disulfide (WS), a two-dimensional adsorbent material, has garnered great attention in removing lead ions (Pb) from water due to their extensive exposed adsorption sites. However, WS nanosheets inevitably agglomerated and stacked during the preparation and adsorption process, leading to reduced adsorption efficiency. Current method of enhancing WS dispersion is mainly blending with synthetic polymers, but these synthetic polymers themselves do not possess adsorption properties, resulting adsorption effect enhancement poorly.
