   Sammanfattning : There has been strong development in the field of diffractive optics (DO) in research laboratories over the past two decades. Much progress has been made, both in design and analysis, as well as in manufacturing techniques. However, so far DO have only reached the market in small numbers. LÄS MER

4. 3. Polymeric Microcavities for Dye Lasers and Wavefront Shapers

   Författare :Sébastien Ricciardi; Ari T. Friberg; Mohamed Bourennane; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical physics; Optisk fysik;

   Sammanfattning : Over the last few years, the available computing power allows us to have a deeper insight into photonics components than we ever had before. In this thesis we use the finite element method (FEM) to explore the behavior of the waves in 2D planar microcavities. LÄS MER
