CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe report on the fabrication and characterization of a two-dimensional photonic crystal (PC) embedding two InGaAs quantum dot layers as active light emitters. Light confinement was provided by both a PC GaAs slab waveguide and a distributed Bragg reflector (DBR) located at the bottom of the guiding layer. The micro-photoluminescence characterization shows that the photonic crystal can be used to alter the quantum dot emission by modifying the photonic density of states.
