Monolithic lithium niobate photonic chip for efficient terahertz-optic modulation and terahertz generation

Nature Communications
The terahertz (THz) range, bridging microwave and infrared frequencies, enables advanced imaging, sensing, communications, and spectroscopy. Analogous to microwave photonics, terahertz photonics offers a promising optical solution to critical THz ...

From Text to Value: Measuring and Pricing Firm Climate Risk Exposure

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine how the prominence and tone of climate risk disclosures affect firm value and strategic climate positioning for large European nonfinancial companies. We developed a firm‐level climate risk exposure (CRE) index that assesses climate risks within corporate narratives across four EU categories: transition risk, physical risk ...

Defining Remanufacturing: A Key Business Strategy Advancing Industrial Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT Remanufacturing is a key strategy in the circular economy, enabling substantial product value retention. However, inconsistent definitions across standards and legislation hinder global trade, core recovery and market acceptance. This study examines how remanufacturing is defined in laws and standards, and how these definitions impact industry

Partially coherent Mathieu–Gauss beams

Scientific Reports
We present a theoretical study and experimental generation of Mathieu–Gauss beams in the partially coherent regime. By means of a rotating ground glass diffuser and a spatial light modulator, we demonstrate independent control over both the spatial ...

Nonlinearity Compensation for Coherent Optical Satellite Communications

CoRR
Optical satellite uplinks rely on high-power optical amplifiers (HPOAs) to overcome free-space attenuation and enable long-distance transmission. However, at high power levels, fiber Kerr nonlinearity becomes significant and degrades system performance.

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

Free-Space Optical Communication Systems with a Partially Coherent Gaussian Beam and Media Diversity

Terrestrial free-space optical (FSO) communications is an emerging low-license-free and high-bandwidth access solution, albeit hampered by the combined effects from atmospheric loss, turbulence and pointing errors (PEs).

Two Hundred Eighty Characters of Environment: Relative Environmental Performance, Strategic Communication, and Firm Value

Business Strategy and the Environment, EarlyView.
ABSTRACT Corporate environmental communication has become an essential aspect of modern business practices, as stakeholders increasingly demand transparency and accountability regarding sustainability efforts. Within this context, we examine whether firms use environmental communication on X/Twitter to offset weaker relative environmental performance ...
