García Ibáñez, Pedro (Universitat Politècnica de València, 2013-02-15)

El objetivo general de este Trabajo Final de Carrera (TFC) se centra en el proceso de automatización de la etapa de configuración de un sistema de criptografía cuántica multiplexado en subportadora de radiofrecuencia. Así ...
Chromatic dispersion compensation and coherent Direct-Sequence OCDMA operation on a single super structured FBG

Baños López, Rocío; Pastor Abellán, Daniel; Amaya Ocampo, Waldimar Alexander; García Muñoz, Víctor (Optical Society of America, 2012)

We have proposed, fabricated and demonstrated experimentally a set of Coherent Direct Sequence-OCDMA en/decoders based on Super Structured Fiber Bragg Gratings (SSFBGs) which are able to compensate the fiber chromatic ...
Desarrollo de un sistema de control y caracterización simultanea de contadores de fotones

Roses Soler, Lorena (Universitat Politècnica de València, 2012-05-25)

The success of Quantum Key Distribution systems and a broad variety of Quantum Optics experiments depends on the ability to detect single photons. In the optical communications third window the most adequate detectors are ...
