Femtosecond Direct Laser Writing of Conductive and Electrically Switchable PEDOT:PSS Optical Nanostructures

open access: yesAdvanced Optical Materials, EarlyView.
Commercial femtosecond direct laser writing (Nanoscribe GT) is utilized to fabricate electrically switchable PEDOT:PSS nanostructures on ITO‐coated glass substrates, as well as underneath and on top of 3D‐printed structures and demonstrates beam‐switching at 1550 nm. Abstract Microscale three‐dimensional (3D)‐printing, with its remarkable precision and

H(II) centers in natural silica under repeated UV laser irradiations

open access: yes, 2004
We investigated the kinetics of H(II) centers (=Ge'-H) in natural silica under repeated 266nm UV irradiations performed by a Nd:YAG pulsed laser. UV photons temporarily destroy these paramagnetic defects, their reduction being complete within 250 pulses.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Low‐Loss Parowax‐Imprinted Diffractive Neural Network for Orbital Angular Momentum Terahertz Holographic Imaging

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of

Enhancement of the Optoelectric and Photovoltaic Responses of Al/PVP:ZnTiO3/p‐Si Structure by Graphene Nanoparticles

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates the optoelectronic response of Al/p‐Si photodiodes with and without a (PVP:Gr‐ZnTiO3) interlayer under varying light intensities. Key parameters are analyzed, revealing that the interlayer enhances photosensitivity, optical responsivity, and specific detectivity.

An Aerial–Aquatic Hitchhiking Robot with Remora‐Inspired Tactile Sensors and Thrust Vectoring Units

open access: yesAdvanced Intelligent Systems, EarlyView., 2023
An untethered aerial–aquatic hitchhiking robot that can be remotely controlled for flying, swimming, and transiting air–water boundaries rapidly (0.16 s), is presented. Notably, it can autonomously attach to various surfaces in both air and water environments using a remora‐inspired suction disc with flexible tactile sensors.
