Information Security Risks Outside the Laser Beam in Terrestrial Free-Space Optical Communication

IEEE Photonics Journal, 2016
Consider a terrestrial free-space optical (FSO) communication system with a potential eavesdropper outside the laser beam who can capture the information through a non-line-of-sight scattering channel.

Semiconductor optical amplifiers for underwater optical wireless communications

IET Optoelectronics, 2017
Underwater optical wireless communications (UOWC) systems have recently received significant attention as an attractive solution for both research and commercial use because of their ability to provide high bandwidth communications over relatively short transmission spans along with their low operational cost. However, high absorption and scattering of

Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

Advanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Legal and ethical considerations around the use of existing illustrations to generate new illustrations in the anatomical sciences

Anatomical Sciences Education, Volume 18, Issue 3, Page 289-300, March 2025.
Abstract It is likely existing anatomical illustrations are often used as the basis for new illustrative works, given not all illustrators have access to human tissues, bodies, or prosections on which to base their illustrations. Potential issues arise with this practice in the realms of copyright infringement and plagiarism when authors are seeking to
