1. III-V semiconductor waveguides for application in nonlinear optics.
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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). LÄS MER
2. Geometry Dependent Optimal Bounds of Absorption and Scattering Cross-section for Small Nanoparticles
Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : Light-matter interaction in particles of subwavelength size mostly depends on the size, shape, composition of the particles and relies on the properties of incident light. Henceforth, resonant behavior of light can be effectively controlled by changing the aforesaid geometrical parameters. LÄS MER
3. Investigating the use of Semiconductor Nanowires for Neural Networks
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. LÄS MER
4. Simulating Microwave Heating for Industrial Processes Using the Finite-Difference Time-Domain Method
Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : Microwave heating is an efficient way of heating compared to conventional industrial alternatives such as autoclaves, a type of pressure cooker commonly used for curing and sterilisation. One problem that limits the adoption of microwave ovens in industrial processes is uneven heating. LÄS MER
5. Towards the detection of single photons in the mid-infrared
Master-uppsats, KTH/Tillämpad fysikSammanfattning : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms. LÄS MER
