SWIPT-Enabled Full-Duplex Short Packet Communications With Nonlinear Energy Harvesting

International Journal of Distributed Sensor Networks
In this work, we examine a simultaneous wireless information and power transfer (SWIPT)–enabled full-duplex (FD) short packet communication system in which both users are equipped with a pair of transmitter–receiver antennas and can transmit and receive ...

Gain Narrowing in Low‐Dimensional PEA:CsPbBr3: Superfluorescence versus Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Superfluorescence is a cooperative emission process not scaling with sample volume. Amplified spontaneous emission is a collective process scaling with sample volume and is enhanced by waveguiding. Both manifest in a narrow emission peak. Choosing the right substrate suppresses waveguiding and demonstrates that the emission feature observed in PEA ...

A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

Advanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced

Seven‐Fold Compression of Mid‐Infrared Pulses Using a Series of Titanium Dioxide Plates

Advanced Optical Materials, EarlyView.
Here, a sequence of three titanium dioxide plates is used to compress a mid‐infrared pulse from 103.9 femtoseconds to 14.1 femtoseconds (about two optical cycles) without the use of external dispersion compensation. The approach maintains high efficiency and produces pulses with a stable carrier‐envelope phase, providing a compact platform for ...

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2

Advanced Optical Materials, EarlyView.
Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.
