1. Photoluminescence Mapping of Erbium Doped Lithium Niobate
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

2. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER
3. Properties of III-V semiconductor materials grown by HVPE
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : This thesis focuses on the characterization of lll-V semiconductor materials by using Scanning Electron Microscopy equipped with Energy Dispersive Spectroscopy (SEM-EDS), High Resolution X-ray Diffraction (HRXRD), Atomic Force Microscopy (AFM) and Photoluminescence (PL). In XRD characterization, the rocking curve measurement was conducted to evaluate the composition of III-V semiconductor alloys and the Reciprocal Lattice Mapping (RLM) revealed the detailed structural properties of heteroepitaxial III-V semiconductors.
