  1. 1. 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
