A photonic microwave filter based on an asymmetric silicon Mach-Zehnder modulator

Gutiérrez Campo, Ana María; Sanchis Kilders, Pablo; Brimont, Antoine Christian Jacques; Thomson, David J.; Gardes, Frédéric Y.; Reed, Graham T.; Fédéli, Jean Marc; Vidal Rodriguez, Borja (Institute of Electrical and Electronics Engineers (IEEE), 2013-08)

[EN] A new approach for implementing an integrable photonic microwave filter based on exploiting the asymmetry of a CMOS-compatible silicon Mach-Zehnder modulator is demonstrated. The strong dependence of the modulator ...
Birefringence effects in multi-core fiber: coupled local-mode theory

Macho-Ortiz, Andrés; García Meca, Carlos; Fraile-Peláez, F. Javier; Morant Pérez, María; Llorente Sáez, Roberto (Optical Society of America, 2016-09-19)

In this paper, we evaluate experimentally and model theoretically the intra- and inter-core crosstalk between the polarized core modes in single-mode multi-core fiber media including temporal and longitudinal birefringent ...
Dynamic control of the operation regimes of a mode-locked fiber laser based on intracavity polarizing fibers: experimental and theoretical validation

Villanueva Ibáñez, Guillermo Eduardo; Pérez Millán, Pedro (Optical Society of America, 2012)

[EN] An intracavity polarizing fiber is proposed to control the emission regime of a passively mode-locked fiber laser. Stable operation in self-starting high and low dispersion soliton mode-locking and 100 GHz multiwavelength ...
Experimental evaluation of nonlinear crosstalk in multi-core fiber

Macho Ortiz, Andrés; Morant Pérez, María; Llorente Sáez, Roberto (Optical Society of America, 2015-07-13)

In this paper we evaluate experimentally and model theoretically the nonlinear crosstalk random process in multi-core fiber. The experimental results indicate that mode coupling in multi-core fibers is reduced in presence ...
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 ...
Nonlinear dispersion-based incoherent photonic processing for microwave pulse generation with full reconfigurability

Bolea Boluda, Mario; Mora Almerich, José; Ortega Tamarit, Beatriz; Capmany Francoy, José (Optical Society of America, 2012)

A novel all-optical technique based on the incoherent processing of optical signals using high-order dispersive elements is analyzed for microwave arbitrary pulse generation. We show an approach which allows a full ...
WDM-Coherent OCDMA over one single device based on short chip Super structured fiber Bragg gratings

Amaya Ocampo, Waldimar Alexander; Pastor Abellán, Daniel; Baños López, Rocío; García Muñoz, Víctor (Optical Society of America, 2011)

We theoretically propose and demonstrate experimentally a Coherent Direct Sequence OCDMA en/decoder for multi-channel WDM operation based on a single device. It presents a broadband spectral envelope and a periodic spectral ...
