  1. 1. III-V semiconductor waveguides for application in nonlinear optics.

    University essay from KTH/Tillämpad fysik

    Author : Andreas Charalampous; [2022]
    Keywords : InGaP; optical waveguides; integrated optics; quantum nonlinear optics; SHG; SPDC; InGaP; optiska vågledare; integrerad optik; icke-linjär kvantoptik; SHG; SPDC;

    Abstract : This thesis presents studies on III-V semiconductor waveguides with particular emphasis on second-order optical nonlinearity. The nonlinear processes that were investigated in this thesis are the Second Harmonic Generation (SHG) and the Spontaneous Parametric Down-Conversion (SPDC). READ MORE

  3. 2. Finite element modelling of strained nanowire heterostructures

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Alexander Grape Wyke; [2019]
    Keywords : Strain; nanowire; heterostructure; physics; nanophysics; COMSOL; simulation; lattice; Physics and Astronomy;

    Abstract : When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. READ MORE

  4. 3. Time-Resolved Photoluminescence Studies of InGaP Nanowires for Improving the Internal Quantum Efficiency

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Lert Chayanun; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. READ MORE

  5. 4. Investigation and design of a wideband microwave VCO

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Nayuan Zhang; [2012]
    Keywords : VCO;

    Abstract : In this thesis, some most popular technologies for both resonator and active device were presented and compared. Two MMIC VCOs were selected to design on InGaP HBT and push push configuration with different topologies, namely balanced Colpitts and balanced Clapp. READ MORE
