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.
EnglishVery high sensitivities can be reached employing 2-PSK based binary sequences for the coherent modulation of an optical carrier. Homodyne detection can be employed, attaining an improvement of 3 dB with respect to usual ultimate sensitivity limits calculated for M-FSK transmission with heterodyne detection, when M tends to infinity. Considering a real receiver, a transmission efficiency as high as 0.4 bit/photon can be reached, at the expense of a bandwidth expansion factor smaller than 6.
