Design of Heterogeneous Multicore fibers as sampled True Time Delay Lines

Garcia, A.; Gasulla Mestre, Ivana (Optical Society of America, 2015-02-15)

We present a novel procedure for designing a sampled discrete true-time delay line (TTDL) for Microwave Photonics applications based on a heterogeneous MCF. Both simple step-index (SI) and trench-assisted SI profiles are ...
Dispersion-engineered multicore fibers for distributed radiofrequency signal processing

García Cortijo, Sergi; Gasulla Mestre, Ivana (Optical Society of America, 2016-08-05)

[EN] We report a trench-assisted heterogeneous multicore fiber optimized in terms of higher-order dispersion and crosstalk for radiofrequency true time delay operation. The analysis of the influence of the core refractive ...
EAM-SOA millimeter-wave frequency up-converter for radio-over-fiber applications

Palací López, Jesús; Villanueva Ibáñez, Guillermo Eduardo; Herrera, J. (Elsevier, 2011-01-01)

[EN] We present an optical scheme for photonic frequency up-conversion at the millimeter-wave bands based on Semiconductor Optical Amplifier. The proposed scheme modulates the bias current with the Intermediate Frequency ...
High-order UWB pulses scheme to generate multilevel modulation formats based on incoherent optical sources

Bolea Boluda, Mario; Mora Almerich, José; Ortega Tamarit, Beatriz; Capmany Francoy, José (Optical Society of America: Open Access Journals, 2013-11-18)

We present a high-order UWB pulses generator based on a microwave photonic filter which provides a set of positive and negative samples by using the slicing of an incoherent optical source and the phase inversion in a ...
Highly chirped single-bandpass microwave photonic filter with reconfiguration capabilities

Bolea Boluda, Mario; Mora Almerich, José; Ortega Tamarit, Beatriz; Capmany Francoy, José (Optical Society of America, 2011)

We propose a novel photonic structure to implement a chirped single-bandpass microwave photonic filter based on the amplitude modulation of a broadband optical signal transmitted by a non-linear dispersive element and an ...
Integrable high order UWB pulse photonic generator based on cross phase modulation in a SOA-MZI

Moreno, Vanessa; Rius Mercado, Manuel; Mora Almerich, José; Muriel Fernandez, Miguel Angel; Capmany Francoy, José (Optical Society of America: Open Access Journals, 2013-09-23)

We propose and experimentally demonstrate a potentially integrable optical scheme to generate high order UWB pulses. The technique is based on exploiting the cross phase modulation generated in an InGaAsP Mach-Zehnder ...
Integrated InP frequency discriminator for Phase-modulated microwave photonic links

Sánchez Fandiño, Javier Antonio; Doménech Gómez, José David; Muñoz Muñoz, Pascual; Capmany Francoy, José (Optical Society of America: Open Access Journals, 2013-02-11)

[EN] We report the design, fabrication and characterization of an integrated frequency discriminator on InP technology for microwave photonic phase modulated links. The optical chip is, to the best of our knowledge, the ...
Multi-cavity Optoelectronic Oscillators using Multicore Fibers

García Cortijo, Sergi; Gasulla Mestre, Ivana (Optical Society of America, 2015-02-09)

We propose the use of both homogeneous and heterogeneous multicore fibers to implement multi-cavity optoelectronic oscillators. We present design equations and examples that show the potential for unique performance in ...
Photonic Techniques for Next-Generation Integrated Optical Networks Based on Ultra-Wideband Radio / Técnicas Fotónicas para Redes Ópticas Integradas de Próxima Generación Basadas en Radio de Banda Ultra Ancha

Beltrán Ramírez, Marta (Universitat Politècnica de València, 2012-05-10)

La presenta Tesis Doctoral encuentra su ámbito de aplicación en redes de acceso ópticas de fibra hasta el hogar o FTTH (del inglés fibre-to-the-home). Las redes FTTH han sido ampliamente desplegadas en todo el mundo y se ...
Photonics-based microwave frequency measurement using a double-sideband suppressed-carrier modulation and an InP integrated ring-assisted Mach Zehnder interferometer filter

Sánchez Fandiño, Javier Antonio; Muñoz Muñoz, Pascual (Optical Society of America, 2013-11-01)

[EN] A photonic system capable of estimating the unknown frequency of a CW microwave tone is presented. The core of the system is a complementary optical filter monolithically integrated in InP, consisting of a ring-assisted ...
