2. 1. Epitaxy of GaAs-based long-wavelength vertical cavity lasers

   Author : Carl Asplund; KTH; []
   Keywords : gainnas; ingaas; quantum wells; movpe; mocvd; vertical cavity laser; bcsel; long-wavelength; epitaxy; xrd; dbr;

   Abstract : Vertical cavity lasers (VCLs) are of great interest aslow-cost, high-performance light sources for fiber-opticcommunication systems. They have a number of advantages overconventional edge-emitting lasers, including low powerconsumption, efficient fiber coupling and wafer scalemanufacturing/testing. READ MORE

4. 2. Epitaxial growth optimization for 1.3-um InGaAs/GaAs Vertical-Cavity Surface-Emitting lasers

   Author : Zhenzhong Zhang; Mattias Hammar; Nicolae Chitica; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; VCSEL MOVPE InGaAs GaAs quantum wells; Semiconductor physics; Halvledarfysik;

   Abstract : Long-wavelength (1.3-μm) vertical-cavity surface-emitting lasers (VCSELs) are of great interest as low-cost, high performance light sources for fiber-optic metro and access networks. During recent years the main development effort in this field has been directed towards all epitaxial GaAs-based structures by employing novel active materials. READ MORE
