Demonstration of elastic optical networks based on OFDM/SCFDM subbands

, 2013
Elastic optical networks (EON) based on OFDM/SCFDM subbands are proposed in this paper. We verify the ROADM and switching functionality for individual subband on optical superchannel that consists of multi subbands.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Optical Comb-enabled Cost-effective ROADM Scheme for Elastic Optical Networks

, 2014
We propose a ROADM Add/Drop scheme based on optical comb for elastic optical networks and experimentally demonstrates the feasibility. The scheme supports wide-range subband to superchannel Add/Drop functionality, while greatly saves network devices ...

Performance of elastic optical network with limited slicers

ICT Express, 2023
A bandwidth blocking occurs due to bandwidth fragmentation in an elastic optical network, which arises from setting up and tearing down of lightpaths. An appropriate routing and spectrum allocation (RSA) approach can reduce this blocking. RSA performs under two allocation rules, which are continuous connection and consecutive slots.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

IDEALIST control and service management solutions for dynamic and adaptive flexi-grid DWDM networks [PDF]

, 2013
Wavelength Switched Optical Networks (WSON) were designed with the premise that all channels in a network have the same spectrum needs, based on the ITU-T DWDM grid.

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.
