Bending and twisting effects on multicore fiber differential group delay

García-Cortijo, Sergi; Ureña-Gisbert, Mario; Gasulla Mestre, Ivana (The Optical Society, 2019-10-28)

[EN] In this paper we provide the theoretical and experimental evaluation of fiber bending and twisting effects on the group delay performance of a homogeneous 7-core fiber. We have experimentally evaluated the differential ...
Demonstration of distributed radiofrequency signal processing on heterogeneous multicore fibres

García-Cortijo, Sergi; Ureña-Gisbert, Mario; Gasulla Mestre, Ivana (IEEE, 2019-09-26)

[EN] We experimentally demonstrate for the first-time to our knowledge distributed radiofrequency signal processing performed by a heterogeneous multicore fibre link. A trench-assisted 7-core fibre, where each core presents ...
Dispersion-Diversity Multicore Fiber Signal Processing

García-Cortijo, Sergi; Ureña-Gisbert, Mario; Gasulla Mestre, Ivana (American Chemical Society, 2022-08-17)

[EN] Beyond playing a primary role in high-capacity communication networks, multicore optical fibers can bring many advantages to optical and microwave signal processing, as not only space but also chromatic dispersion are ...
Estudio del régimen de propagación no lineal en guías de nitruro de silicio

Ureña Gisbert, Mario (Universitat Politècnica de València, 2017-11-29)

In this work the study of the nonlinear propagation regime in integrated optical waveguides is carried out, with special emphasis on waveguides with silicon nitride core. Recently an increasing interest in this material ...
Experimental demonstration of dispersion-diversity multicore fiber optical beamforming

Ureña-Gisbert, Mario; García-Cortijo, Sergi; Herranz Herruzo, José Ignacio; Gasulla Mestre, Ivana (The Optical Society, 2022-08-29)

[EN] Phased array antenna (PAA) beam-steering in high radiofrequency bands will be key for upcoming 5G & Beyond wireless communications systems. As a compact and efficient solution to provide tunable beam steering ...
Modeling optical fiber space division multiplexed quantum key distribution systems

Ureña-Gisbert, Mario; Gasulla Mestre, Ivana; Fraile, Francisco Javier; Capmany Francoy, José (The Optical Society, 2019-03-04)

[EN] We report a model to use to evaluate the performance of multiple quantum key distribution (QKD) channel transmission using spatial division multiplexing (SDM) in multicore (MCF) and few-mode fibers (FMF). This model ...
Novel Multicore Optical Fibers for Signal Distribution and Processing

Ureña Gisbert, Mario (Universitat Politècnica de València, 2023-09-07)

[ES] Las fibras de multiplexación por división espacial surgieron en la última década como solución al cuello de botella en la capacidad en las redes de comunicación de fibra óptica monomodo. Utilizan el espacio, la última ...
Photonic-Assisted Analog-to-Digital Conversion Based on a Dispersion-Diversity Multicore Fiber
