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.

Automatic Hidden Elastic Optical Bypasses in Multi-Layer Networks

Applied Sciences
This paper focuses on handling traffic demands dynamically in a multi-layer IP-over-elastic optical network (IP-over-EON). We propose a mechanism that uses two types of optical resources.

Performance Analysis of Automatic Hidden Ligthpaths in Multi-Layer Networks

Photonics, 2023
The problem of resource provisioning in multi-layer networks is an important issue. We discuss and analyze resource provisioning in terms of the visibility of optical resources for the virtual layer in a network.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Confidentiality meets protection in elastic optical networks

Optical Switching and Networking, 2021
Abstract This work considers the joint problem of securing confidential demands against eavesdropping attacks and protecting the network against link failures in elastic optical networks (EONs). Network coding is used to provide security for confidential connections by encrypting the data through XOR operations at the physical layer with other ...

Using static connections to improve elastic optical networks performance

, 2017
Network resources are poorly used in Elastic Optical Networks under dynamic traffic conditions. A hybrid scheme where some resources are statically allocated and the remaining ones are devoted to dynamic traffic, is proposed and evaluated.Peer ...
