Coherent and incoherent crosstalk in WDM optical networks
Yunfeng Shen,Kejie Lu,Wanyi Gu +2 more
TL;DR: In this article, the impact of coherent and incoherent crosstalk on an optical signal passing through optical cross-connect nodes (OXC's) in WDM optical networks is studied, and the analytical expressions are given.
Journal ArticleDOI
Continuous-variable measurement-device-independent quantum key distribution using squeezed states
TL;DR: It is found that there is an optimal added noise to optimize the performance of the CV-MDI QKD protocol in terms of both key rates and maximal transmission distances.
Journal ArticleDOI
A simple method for fabricating p–n junction photocatalyst CuFe2O4/Bi4Ti3O12 and its photocatalytic activity
TL;DR: In this article, the p-n heterojunction photocatalyst CuFe2O4/Bi4Ti3O12 was obtained through ball milling and the structures, morphologies, and optical properties of the photocatalysts were comprehensively characterized.
Journal ArticleDOI
Measurement of the rotational Doppler frequency shift of a spinning object using a radio frequency orbital angular momentum beam.
TL;DR: An indirect approach based on phase measurement is proposed to measure the rotational Doppler frequency shift, which takes full advantage of the phase structure of orbital angular momentum (OAM) beams in radio domain, using a vector network analyzer (VNA) as a phase discriminator.
Journal ArticleDOI
Nonparameter Nonlinear Phase Noise Mitigation by Using M-ary Support Vector Machine for Coherent Optical Systems
TL;DR: The M-ary support vector machine (SVM) is introduced as a nonparameter nonlinear phase noise (NLPN) mitigation approach for the coherent optical systems and performs better than the method of amplitude-dependent phase rotation at the transmitter and receiver.
