Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

Advanced Optical Materials, EarlyView.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

Ultrabroadband Excitation of Hot Carriers in Plasmonic Nanorods Revealed by Two‐Dimensional Electronic Spectroscopy

Advanced Optical Materials, EarlyView.
This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Color-Selective Channel Modeling for Visible Light Communication (VLC)

IEEE Access
Color-selective attenuation, a specific case of wavelength- or frequency-selective attenuation, is an under-investigated but significant factor affecting the performance of color-modulated systems, particularly in Non-Line-of-Sight (NLOS) links ...

Tunable Patterned Blue Phase Liquid Crystals Based on Lithographic Process Technology

Advanced Optical Materials, EarlyView.
A patterned blue phase liquid crystal device with electrically driven, localized bistability is demonstrated using a cost‐efficient photolithographic dual‐alignment process. The device switches between a high‐contrast patterned state and a uniform reflective state.

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing

Advanced Optical Materials, EarlyView.
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Rapid multi-band space-based optical timing: revolutionizing accretion physics

Frontiers in Astronomy and Space Sciences
Optical timing with rapid, seconds-to-minutes cadences with high photometric precision and gap-free long baselines is necessary for an unambiguous physical picture of accretion phenomena, and is only possible from space.

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

Advanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Nb2CBr2 MXene Monolayer as a Novel Material: A First Principle Study

Advanced Theory and Simulations, EarlyView.
Illustration of the monolayer cell, cell replicated in directions a and b, graph of optical absorption and thermodynamic potentials as a function of temperature. Abstract Niobium‐based MXenes show promising properties and applications, but have not yet been sufficiently investigated, especially with halogen surface terminations. This study investigates
