Dissertation Multilayer Thin-film Structures with Distributed Cavity for Optical Filter and Laser Applications 

Taimoor, Muhammad (2018-12)
This work is aimed at the development of a fabrication process for realization of a chirped filter based laser device (called as coreSEL). Conventional vertical cavity surface emitting lasers (VCSELs) are based on Fabry-Pérot arrangement where the electric field of the resonant mode is mainly located in the cavity region (center) and often causes undesired effects such as mode-jumps. However, coreSEL is based on chirped optical filter which offers a resonant mode with wider spatial distribution of the electric field ...

Dissertation Model Calculations for Characterisation and Implementation of Vertical Thin-Layer Structures with Distributed Cavity Mode for Filter and Laser Applications 

Reuter, Sabrina (2018-04-11)
This work focusses on the approach of optical thin-layer filters with distributed cavity mode. Fabry-Pérot filters own a single cavity layer in the centre of the stack. In contrast, with chirped filter approach the cavity thickness is distributed over several layers. Model calculation results are applied to characterise the properties of the spectrum and the electric field of chirped filters. The aim of distributing the cavity within the filter stack is to distribute the electric field in the resonance case (transmission ...
