[EN] We propose and experimentally demonstrate the use of directional couplers with an independent phase actuator on each waveguide. We show the configurations that allow the setting of the splitting ratio and the phase ...

The Split Ring Resonator (SRR) is a basic element in nanophotonics since it allows to obtain negative magnetic permeabilities at optical frequencies. In this way, metamaterials can be obtained from SRR arrays with responses ...

[EN] Microwave photonic (MWP) links and systems will have more losses as their complexities increase and there will be a need for incorporating optical amplification. Here, we report results of an analytical model developed ...

[ES] La fotónica de microondas, la cual une los mundos de la ingeniería de radiofrecuencia y la optoelectrónica, ha generado un gran interés en las últimas décadas. Su valor añadido se deriva del hecho de que, por un lado, ...
