  2. 21. Modulation Properties of Vertical Cavity Light Emitters

    Author : Renaud Stevens; KTH; []
    Keywords : Semiconductor lasers; VCSEL; high-speed modulation; fibre optic networks; datacom; RCLED; plastic optical fibre;

    Abstract : It is estimated that, between the year 2000 and 2003, thenumber of online Internet users will grow from 250 millions to500 millions. This growth results in rapidly increasing demandfor fibre-optic communication bandwidth, occurring at alllevels: from access and local area networks (LANs) tometro-area networks (MANs). READ MORE
