    Author : Stefan Rapp; KTH; []
    Keywords : ;

    Abstract : Vertical-cavity surface-emitting lasers (VCSELs) operatingat long wavelength (1.3-1.55µm) are of great interest asinexpensive, high-performance light sources for opticalcommunication systems. READ MORE

  6. 4. Development of 1.3-μm GaAs-based vertical-cavity surface-emitting lasers

    Author : Petrus Sundgren; Mattias Hammar; Harri Lipsanen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik;

    Abstract : Long-wavelength vertical-cavity surface-emitting lasers (VCSELs) are desirable as low-cost sources for optical metropolitan-area and access networks. In the development of 1.3-µm VCSELs, most attention today is given to monolithic GaAs-based solutions, although no established active material exists in this wavelength region. READ MORE
