  1. 1. Modulation Properties of Vertical Cavity Light Emitters

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

    Sammanfattning : 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). LÄS MER

  3. 2. Processing technologies for long-wavelength vertical-cavity lasers

    Författare :Fredrik Salomonsson; KTH; []
    Nyckelord :VCSEL; vertical-cavity laser; semiconductor laser; long-wavelength; DBR; oxidation; wafer fusion; InGaAs; semiconductor processing;

    Sammanfattning : Vertical-cavity surface-emitting lasers (VCSELs) areattractive as potential inexpensive high-performance emittersfor fibre-optical communication systems. Their surface-normalemission together with the small dimensions are beneficial forlow-cost fabrication since it allows on-wafer testing,simplified packaging and effective fibre-coupling. LÄS MER
