“…The designed circuits were implemented using a MMIC PH15 process from United Monolithic Semiconductors (UMS). A modular semi-analytical tool was also developed, for the noise characterization of distributed optical preamplifiers for very high-capacity optical transmission [30,31] and a 45 GHz distributed MMIC amplifier implemented [32]. Due to the high potential of the OSSB transmission, a new project ETOBLU has been recently funded by a telecommunication equipment manufacturer (Siemens S.A.) to study the applicability and implementation of optical single sideband transmission for the next generation telecommunication equipment at 10 and 40 Gbit/s.…”
