Compact multichannel demultiplexer for WDM-POF networks based on spatially overlapped FBGs

Sáez-Rodríguez, D; Nielsen, K; Bang, O.; Ortega Tamarit, Beatriz (Institution of Electrical Engineers, 2016)

[EN] The fabrication of spatially overlapped fibre Bragg gratings over microstructured polymer optical fibre allows to demonstrate low-cost and compact multichannel wavelength division demultiplexers. Coarse and dense ...
Experimental Demonstration of Extended 5G Digital Fronthaul Over a Partially-Disaggregated WDM/SDM Network

Fabrega, Josep M.; Múñoz, Raúl; Nadal, Laia; Manso, Carlos; Svaluto Moreolo, Michela; Vilalta, Ricard; Martínez, Ricardo; Vílchez, Francisco Javier; Pérez-Galacho, Diego; Sales Maicas, Salvador; Grivas, Evangelos; Turkiewicz, Jaroslaw P.; Rommel, Simon; Tafur Monroy, Idelfonso (Institute of Electrical and Electronics Engineers, 2021-09)

[EN] We experimentally demonstrate a 5G digital fronthaul network that relies on multi-adaptive bandwidth/bitrate variable transceivers (BVTs) and an autonomic software-defined networking (SDN) control system for ...
Overlap-proof Fiber Bragg Grating Sensing System using Spectral Encoding

Triana-Infante, Cristian Andres; Pastor Abellán, Daniel; Varón, Margarita (Institute of Electrical and Electronics Engineers (IEEE), 2016-04-01)

In this letter, a spectral encoding of fiber Bragg grating (FBG) sensors is proposed in order to solve their wavelength under overlapping conditions. Our technique uses optical orthogonal codes (OOCs) to define the spectral ...
Performance Comparison Between 4D Trellis Coded Modulation and PAM-4 for Low-Cost 400 Gbps WDM Optical Networks

Prodaniuc, Cristian; Stojanovic, Nebojsa; Karinou, Fotini; Qiang, Zhang; Llorente Sáez, Roberto (Institute of Electrical and Electronics Engineers, 2016)

[EN] We investigate two trellis-coded modulation (TCM) schemes for use in next-generation low-cost 400G optical networks. Their performance is evaluated against that of four-level pulse amplitude modulation (PAM-4). We ...
Photonic multiple millimeter wave signal generation and distribution overreconfigurable hybrid SSMF/FSO links

Vallejo-Castro, Luis; Ortega Tamarit, Beatriz; Bohata, Jan; Zvanovec, Stanislav; Almenar Terre, Vicenç (Elsevier, 2020-01)

[EN] Microwave photonics provides attractive solutions for millimeter wave (mmW) signal generation. In this paper, we demonstrate photonically generated multiple mmW signals transmission over a wavelength division multiplexed ...
Reconfigurable Reflective Arrayed Waveguide Grating on Silicon Nitride

Fernández Vicente, Juan (Universitat Politècnica de València, 2021-04-29)

[ES] La presente tesis se ha centrado en el modelado, diseño y demonstración experimental por primera vez del dispositivo Reconfigurable Reflective Arrayed Waveguide Grating (R-RAWG). Para la consecución de este dispositivo ...
