A monolithic integrated photonic microwave filter

Sanchez Fandiño, Javier Antonio; Muñoz Muñoz, Pascual; Doménech Gómez, José David; Capmany Francoy, José (Nature Publishing Group, 2017-02)

[EN] Meeting the increasing demand for capacity in wireless networks requires the harnessing of higher regions in the radiofrequency spectrum, reducing cell size, as well as more compact, agile and power-efficient base ...
Bidirectional WDM-OOFDM access network based on a sliceable optical transceiver with colorless ONUs

Sekkiou, Imene; Chicharro López, Francisco Israel; Ortega Tamarit, Beatriz; Mora Almerich, José (Elsevier, 2018)

[EN] A WDM OOFDM access network using a centralized optical transceiver based on a single optical broadband sliced source at the Central Office is presented as a low cost solution. Such network offers downlink and uplink ...
Impact of Thermal-Induced Turbulent Distribution Along FSO Link on Transmission of Photonically Generated mmW Signals in the Frequency Range 26¿40 GHz

Vallejo-Castro, Luis; Komanec, Matej; Ortega Tamarit, Beatriz; Bohata, Jan; Nguyen, Dong-Nhat; Zvanovec, Stanislav; Almenar Terre, Vicenç (Institute of Electrical and Electronics Engineers, 2020-02)

[EN] Microwave photonics is a promising solution to transmit millimeter wave (mmW) signals for the 5th generation (5G) mobile communications as part of a centralized radio access network (C-RAN). In this paper, we ...
Integrated Microwave Photonics for Radio Access Networks

Capmany Francoy, José; Muñoz Muñoz, Pascual (Institute of Electrical and Electronics Engineers, 2014)

[EN] We explore the advantages that integrated microwave photonics (IMWP) can bring to access networks. We first of all review the most common architectures of radio access networks (RANs) to identify the segments where ...
On the Conditions that Justify Dynamic Reconfigurability in WDM-TDMA Optical Access Networks

García Roger, David; Artundo Martínez, Iñigo; Ortega Tamarit, Beatriz (The Optical Society, 2011)

[EN] In a passive optical network with a hybrid wavelength division multiplexing time division multiple-access scheme, implementing reconfigurable wavelength assignment is complex; hence the need to determine the ...
Proyecto de infraestructura de acceso FTTH en la ciudad de Rotterdam

Ramón Honrubia, Pablo (Universitat Politècnica de València, 2022-04-07)

[ES] Este TFG se centra en un proyecto real de ingeniería de telecomunicaciones realizado en la ciudad de Rotterdam (Países Bajos) en la empresa The People Group a demanda del cliente Van Gelder Telecom. Se realizará un ...
Técnicas de conformación de haces para redes ópticas de acceso híbridas 5G/6G en la banda de ondas milimétricas

Botella Campos, Marta (Universitat Politècnica de València, 2021-10-11)

[ES] El objetivo de este trabajo será sentar las bases para la futura tesis doctoral en conformación de haces para redes de acceso ópticas híbridas de cable/inalámbricas. En concreto, el trabajo consistirá en estudiar las ...
Wavelength-Offset Filtering in Optical OFDM IMDD Systems Using Directly Modulated DFB Lasers

Wei, J. L.; Sánchez Costa, Christian; Hugues-Salas, E.; Spencer, P. S.; Tang, J. M. (Institute of Electrical and Electronics Engineers (IEEE), 2011)

[EN] In optical OFDM (OOFDM) intensity-modulation and direct-detection (IMDD) single-mode fibre transmission systems using directly modulated DFB lasers (DMLs), wavelength-offset optical filtering considerably improves ...
