Quantum teleportation over the Swisscom telecommunication network [PDF]

open access: yes, 2006
We present a quantum teleportation experiment in the quantum relay configuration using the installed telecommunication network of Swisscom. In this experiment, the Bell state measurement occurs well after the entanglement has been distributed, at a point

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

open access: yesAdvanced Materials, EarlyView.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Enhancing Stability of Few‐Layer Black Phosphorus (FLBP) Through Nitrocellulose Coating: A Robust Defense Mechanism Against Degradation

open access: yesAdvanced Materials Interfaces, EarlyView.
In this research, a simple and scalable strategy for protection of a few‐layer black phosphorus (FLBP) with a cellulose nitrate‐based material is presented. The FLBP is structurally and morphologically characterized. The FLBP stability with and without nitrocellulose protection is monitored by interferometric method, surface profile examination, and ...

Spoof Surface Plasmon Polaritons Fed Frequency-Scanning Open-Loop Antenna Arrays

open access: yesIEEE Access, 2019
Spoof surface plasmon polaritons (SSPPs) fed open-loop elements without a metallic ground plane are investigated for the SSPPs-based antenna design. By employing a straight SSPPs section close to the open end of the loop as the feed, the one-wavelength ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Drawing telecommunication networks [PDF]

open access: yes, 1995
The design and analysis of cost effective survivable telecommunication networks is a very important problem. We study techniques for visualizing survivable telecommunication networks. The visualization of telecommunication networks is very useful in aiding the design process of minimum cost networks and the management of network operations.

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...
