Experimental all-optical relay-assisted FSO link with regeneration and forward scheme for ultra-short pulse transmission
(Optical Society of America, 2019)
This paper presents experimental results for an all-optical free-space optical (FSO) relay-assisted system by employing an all-optical regenerate and forward (AORF) scheme in order to increase the transmission link span. ...
Radio over 50 km Fiber and Joint 80 m FSO/Wireless Links Using Photonic Frequency Doubling for 5G
(American Institute of Physics and Magnetic Society of the IEEE, 2019)
We present the experimental demonstration of photonic doubling to achieve 25 GHz millimeter wave signal generation, following the 5th generation network frequency band recommendations. A hybrid optical network combining ...
Optical Hybrid Fiber/Free-Space and 25 GHz Wireless Transmission using LTE M-QAM Signals
(Instituto de Telecomunicaçoes - Lisboa, 2019)
We experimentally demonstrate a seamless hybrid transmission of radio-over-fiber (RoF), radio-over-free-space optics (RoFSO) and millimeter wave wireless link using long-term evolution (LTE) 4/16/64-QAM signals for broadband ...
Visible light communications: multi-band super-Nyquist CAP modulation
(Optical Society of America, 2019)
In this paper, we experimentally demonstrate the performance of a non-orthogonal multi-band super-Nyquist carrier-less amplitude and phase (m-SCAP) modulation for visible light communications (VLC). We break the orthogonality ...
Ultra-wideband mid-infrared supercontinuum generation in liquid-filled circular photonic crystal fiber
(SPIE - International Society for Optical Engineering, 2020)
We numerically demonstrate ultra-wideband mid-infrared supercontinuum (SC) generation in a liquid-filled arsenic–selenide circular photonic crystal fiber (C-PCF). The inner ring air-holes are filled with two different ...
M-QAM transmission over hybrid microwave photonic links at the K-band
(Optical Society of America, 2019)
Two experimental configurations of a hybrid K-band (25 GHz) microwave photonic link (MPL) are investigated for seamless broadband wireless access networks. Experimental configurations consist of optical fiber, free-space ...
Interference cancellation in MIMO NLOS optical-camera-communication-based intelligent transport systems
(Optical Society of America, 2019)
The ever-increasing number of vehicles on a global level signifies the need for communications between vehicles and the surrounding environment. Visible light communications (VLC) is a viable complementary technology to ...
Mitigation of dispersion and turbulence in a hybrid optical fibre and free-space optics link using electronic equalisation
(German Society for Applied Optics, 2019)
Transmission of a 25 Gbps non-return to zero signal over a hybrid link of 20 km standard single-mode fibre and 500 m free-space optics under weak-to-moderate turbulence regimes is demonstrated via simulation to provide a ...
Exact modeling of photonic crystal fibers for determination of fundamental properties
(ELSEVIER SCIENCE INC, 2020)
We present a simple but highly accurate modeling technique for real photonic crystal fibers (PCFs) characterization. We determine the influence caused by idealized model parameters. Our technique can be applied to arbitrary ...
Experimental analysis of a triple-hop relay-assisted FSO system with turbulence
(Elsevier Science Publishers B.V., 2019)
This paper outlines experimental investigation of the performance of the wireless optical network based on an all-optical triple-hop free space optical (FSO) communications employing amplify-and-forward relaying under the ...
