Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface

open access: yesAdvanced Optical Materials, EarlyView.
Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.

Topological Valley Photonic Waveguides: Scattering Matrix Evaluation for Linear Computing

open access: yesAdvanced Photonics Research, EarlyView.
This research is focused on the design of a 6‐port junction via valley photonic crystal waveguides to achieve equal power splitting of an incident signal towards three other ports. An in‐depth study is carried out to extract its corresponding scattering matrix.

Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, EarlyView.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital
