[EN] Beam profiling in terahertz systems based on a 4f configuration is revised to show that usual practices underestimate the beam waist due to the narrow point spread function of the detection arm. A rigorous assessment ...

[EN] The application of Allan variance to characterize the stability of optical signals affected by stochastic polarization fluctuations and the identification of the underlying power law noise processes is explored. Allan ...

A general model of analog microwave photonic links employing cascaded amplitude and phase external modulation is theoretically derived. Chromatic dispersion is also included in the model showing a different dispersion ...

[ES] Se propone la realización de un TFM que tiene como objetivo analizar e implementar el protocolo TR-069 en entornos GPON utilizando recursos de código abierto. Se comenzará con un estudio de los entornos ACS y la ...

Los objetivos a alcanzar vienen marcados por el análisis comparativo entre distintos algoritmos de Chroma Key en Matlab, la optimización de los algoritmos implementados y la identificación de las técnicas de las imágenes ...

A method for obtaining the average refractive indexes of a birefringent material in the terahertz region in a single measurement with a standard terahertz time-domain spectrometer is presented. The method is based on ...

[EN] The manipulation of the polarization properties of light in guided media is crucial in many classical and quantum optical systems. However, the capability of current technology to finely define the state of polarization ...

[EN] A nonlinear method to generate and control both the type and magnitude of the birefringence, as well as differential group delay (DGD) in optical fibers is studied. Experiments show that both parameters of birefringence ...
