We report on a vertical adiabatic transition between silica planar waveguides and electro-optic (EO) polymer. Gray-scale lithography was used to pattern a polymer transition with an exponential profile. Excess losses of the order of 1 dB were measured, and good mode matching to simulation was observed. This configuration, which married the advantages of both silica and EO-polymer planar-optic technologies, demonstrates a new technique for fabricating hybrid active devices with high modulation speed, low insertion loss, and complex geometries.

Each cell in the human body is continually exposed to harmful external and internal factors. During evolution, cells have developed various defence systems, divided into enzymatic and non-enzymatic types, to which low-weight molecule antioxidants belong. In this article, the ionisation potential and electron affinity, as well as global reactivity descriptors of Vitamin C, Melatonin, Uric Acids, and N-acetyl-L-cysteine, were theoretically investigated at the MP-2/aug-cc-pVTZ level of theory in the condensed (aqueous) phase.

Electron-nuclear coupling plays a crucial role in strong laser induced molecular dissociation dynamics. The interplay between electronic and nuclear degrees of freedom determines the pathways and outcomes of molecular fragmentation. However, a full quantum mechanical treatment of electron-nuclear dynamics is computationally intensive.

We obtained the photoelectron spectra of Rh(CN) using the negative ion photoelectron velocity-map imaging (NI-PEVMI) technique and revealed the photodesorption process of Rh(CN). The vertical detachment energy (VDE) and adiabatic detachment energy (ADE) of Rh(CN) have both been experimentally reported to be 2.04 (3) eV.
