InGaN photovoltaic converters: Processing approaches for high-power optical transmission

Materials Science in Semiconductor Processing
This work explores the processing of InGaN semiconductors as high-power optical transmission (HPOT) photovoltaic converters (OPCs). Current HPOT systems present limitations in efficiency and power density, primarily due to materials with low band gaps, such as GaAs, with significant losses at high irradiances due to series resistance issues.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Ultra-high speed, all-optical wavelength converters using single SOA and SOI photonic integrated circuits [PDF]

, 2010
We report a new family of ultra-fast all-optical wavelength converters. The device architecture employs a single SOA and filtering elements integrated in silicon-on-insulator substrates.

Tolerable performance of silicon photonic optical-serial-to-parallel converter with variable power splitter

Optics Express, 2018
We have proposed and investigated the tolerable performance of an optical serial-to-parallel converter with phase operation (OSPC) with lower power consumption than the conventional scheme for the purpose of achieving reduction of both the processing load and the processing latency of the high-speed packet switching systems in the data center.
