3D polarized modulation: system analysis and performance
(2018-06-26)
Article
Accés obertIn this paper we present a novel modulation technique for dual polarization communication systems, which reduces the error rate compared with the existent schemes. This modulation places the symbols in a 3D constellation, ... -
Análisis de la propagación monomodal en guías electroópticas multicapa
(Institución ferial de Madrid (IFEMA), 1988)
Text en actes de congrés
Accés obertThe propagation modes in plane electrooptical multilayer waveguides have been calculated. The results have been applied to analyze four layer waveguides. Single mode propagation conditions have been obtained and mode ... -

Brightness enhancement in Non-Hermintian VCSELs
(Optical Society of American (OSA), 2019)
Text en actes de congrés
Accés restringit per política de l'editorialVertical Cavity Surface Emitting lasers (VCSELs) are compact and efficient light sources useful for a variety of applications. However, due to lack of a transverse mode control mechanism, such lasers suffer from poor spatial ... -

Realitzat a/amb: Centro para la Investigación y Rehabilitación de las Ataxias HereditariasEste proyecto final de carrera consiste en el diseño y construcción de un sistema de adquisición de biopotenciales de bajo coste para captar y visualizar la señal electrooculográfica (EOG) y ser usado en el diagnóstico de ... -
Experimental demonstration of multi-vendor and multi-domain elastic optical network with data and control interoperability over a pan-european test-bed
(2016-04-01)
Article
Accés obertThe operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended ... -
General Equations for the Induced Phase Shift in Resonant Electro-Optic Modulators
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-02-28)
Article
Accés obertWe derive general equations to calculate the electrooptically induced optical phase shift in resonantly enhanced modulators. The equations are useful in designing modulator electrodes with optimal length and optimal mismatch ... -
Improved design of all-optica half subtractor based 2 - dimensional photonic crystal
(International Journal of Advance Engineering and Research Development (IJAERD), 2019-03-01)
Article
Accés obertAbstract- Forthcoming Optical computers and Optical Signal Processors need all-optical devices in order to get rid of from Optical-Electrical-Optical conversions; Optical gates play a vital role in Optical networks. Photonic ... -
Micro-nano structured electro-optic devices in LiNbO3 for communication and sensing
(Universitat Politècnica de Catalunya, 2012-02-20)
Tesi
Accés obertA material that is enabling integrated optics is the ferroelectric crystal Lithium Niobate (LiNbO3), which has excellent electro-optical, acousto-optical and nonlinear optical properties. Moreover, it can be doped with ... -
