   Sammanfattning : 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.

   Nyckelord :Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

   Sammanfattning : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. LÄS MER

4. 3. Generation of Short Intense Terahertz pulses Through Optical Rectification

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Carl Ekström; [2015]
   Nyckelord :Terahertz; THz; Optical Rectification; OR; Photonics; Optics; LiNbO3; Physics and Astronomy; Technology and Engineering;

   Sammanfattning : The lack of sources that generates intense THz pulses have in many years limited the field of THz science. Until recently intense THz pulses have been hard to generate using nonlinear crystals such as Lithium Niobate (LiNbO3) with high efficiency. LÄS MER

7. 5. Influence of selective proton exchange on periodically poled lithium niobate

   Master-uppsats, KTH/Laserfysik

   Författare :Michele Manzo; [2010]
   Nyckelord :;

   Sammanfattning : The purpose of the present thesis is to study the influence of Proton Exchange on Electric Field assisted Poling of congruent Lithium Niobate and its applications on periodically patterned structures. Moreover, the possibility of using Proton Exchange to avoid neighbours domains merging is studied and successfully demonstrated for period shorter than 10μm. LÄS MER
