  1. 1. Long-Wavelength Vertical-Cavity Lasers : Materials and Device Analysis

    Författare :Sebastian Mogg; KTH; []
    Nyckelord :VCL; VCSEL; vertical-cavity laser; semiconductor laser; long-wavelength; DBR; characterization; analysis; InP; InGaAs; quantum well; numerical modeling;

    Sammanfattning : Vertical-cavity lasers (VCLs) are of great interest as lightsources for fiber-optic communication systems. Such deviceshave a number of advantages over traditional in-plane laserdiodes, including low power consumption, efficient fibercoupling, on-chip testability, as well as potential low-costfabrication and packaging.

  2. 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
