[ANGLÈS] We have investigated a highly efficient source of polarization-entangled photons for long-distance free-space communication and other experiments involving significant propagation loss. The source is an evolution ...

High-resolution time measurement is a fundamental building block on a wide variety of applications such as time-of-flight based systems, single-photon microscopy and quantum communications. FPGA-based TDCs are the preferred ...

Liquid crystal (LC) devices are increasingly attracting much interest for applications where an electrical control of light is required. In this work, a nematic LCbased optical deflector has been designed, fabricated and ...

[ANGLÈS] In this thesis, the design, fabrication and characterization of thermal optical probes based on Fiber Bragg Gratings are presented. The main focus was the optimization and manufacturing of a proper package for ...

In this thesis, we demonstrate the correct operation of a fluorescence sensor designed for the analysis of water samples, in concrete phytoplankton levels and microorganism counting. The system, based on different techniques ...

En este proyecto se describe la investigación en el campo de la optoelectrónica (nexo de unión entre los sistemas ópticos y eléctricos) vinculada a nuevos materiales y metodologías aplicadas a electrodos transparentes. Estos ...

Ultrathin materials emerged as game changers for Optoelectronics industry for integrated circuits, transis- tors, solar cells, light emitting diodes, photoconductors, light crystal displays and many other applications. In ...

(English) There is currently significant scientific and technological interest in ultrathin materials, with at least one dimension in the nm range or even smaller, since they possess features not achievable with their ...

The project aims at developing new photonic transmitters for quantum cryptography applications which could be used to increase the security of communication networks. The transmitter will be designed to generate security ...
