Photonic Unitary Circuits for Quantum Information Processing

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Unitary transformations are the cornerstone of quantum computing, enabling reversible manipulation of quantum states. This review evaluates photonic waveguide architectures as an evolving solution for quantum computing, exploiting the unique properties of photons. It investigates current theoretical frameworks, material platforms, and design strategies.

Enhancing the performance of AlGaN-based DUV-LEDs with multifocal laser stealth dicing

Optics Express
In this study, AlGaN-based deep-ultraviolet light-emitting diodes (DUV-LEDs) processed via standard laser dicing (SLD) and multifocal laser stealth dicing (MFLSD) were investigated. Adopting the MFLSD technology would generate a roughing surface rather than the V-shaped grooves on the sidewall of 508 × 508 µm2 DUV-LEDs, which would reduce the forward ...

Characterization of the Nature of Organic Matter in Carbonate Rocks: Implications for Geological and Environmental Studies

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Organic matter in carbonate rocks plays a crucial role in processes such as fluid flow regulation, carbon sequestration, contaminant transport, and hydrocarbon recovery. This study employed multimodal spectroscopic techniques, including fluorescence imaging and Fourier transform infrared (FTIR) spectroscopy, to characterize the spatial ...

Planar unclustered scale-free graphs as models for technological and biological networks

, 2009
Many real life networks present an average path length logarithmic with the number of nodes and a degree distribution which follows a power law. Often these networks have also a modular and self-similar structure and, in some cases - usually associated ...

Enhanced the Optical Power of AlGaN-Based Deep Ultraviolet Light-Emitting Diode by Optimizing Mesa Sidewall Angle

IEEE Photonics Journal, 2018
In this work, we propose and optimize the sidewalls for the mesa to enhance the optical power for AlGaN-based deep ultraviolet light-emitting diodes (LEDs). We obtain the mesa with the inclined sidewalls by conducting dry etching. The optical performance

A new Manifestation of Atomic Parity Violation in Cesium: a Chiral Optical Gain induced by linearly polarized 6S-7S Excitation

, 2002
We have detected, by using stimulated emission, an Atomic Parity Violation (APV) in the form of a chiral optical gain of a cesium vapor on the 7S - 6P$_{3/2}$ transition,consecutive to linearly polarized 6S-7S excitation.
