    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor laser; molecular beam epitaxy; InGaAs quantum well; graded buffer layer; metamorphic heterostructures;

    Sammanfattning : The development of fiber-optical networks for broad-band access is expected to create a huge market for laser transmitters in the 1.3-1.55 µm wavelength range. The existing InP-based lasers have poor temperature stability. LÄS MER

  3. 2. Metamorphic Heterostructures and Lasers on GaAs

    Författare :Ivar Tångring; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; metamorphic heterostructures; InGaAs quantum well; graded buffer layer; Semiconductor laser; GaAs; molecular beam epitaxy; telecom laser;

    Sammanfattning : The objective of this thesis is to demonstrate the metamorphic growth of heterostructure lasers on GaAs substrates. Many heterostructure devices have their performance limited by the need to grow on lattice-matched substrates. LÄS MER
