Design and characterization of silicon photonics integrated components for optical networks

• Si propone una struttura integrata per il filtraggio dei canali per telecomunicazioni ottiche su sistemi WDM. Questa struttura è composta da un accoppiatore a due guide con perturbazioni periodiche di indice. Attraverso il controllo delle proprietà delle guide tramite materiali a transizione di fase si può controllare la risposta in uscita, permettendo demultiplexing elastico e non-volatile, (2024)
