1. Grating-Coupled Surface-Emitting Lasers -- Circular and Unstable-Resonator Geometries
Abstract : This thesis deals with research in the field of grating-coupled surface-emitting lasers. The emphasis has been to study the modal behavior of lasers with two different resonator geometries: circular resonators and tapered unstable-resonators. READ MORE

3. Grating Based Lasers for Photonic Integration and Surface Emission
Abstract : This thesis deals with the fabrication and characterization of grating-based integration-compatible semiconductor lasers. Waveguide gratings provide feedback for the laser resonators, and are used to diffract the laser output out of the waveguide for surface-emission. READ MORE

4. Grating-Coupled Surface-Emitters --- Highly Directional Outcouplers and Spatially Coherent Lasers
Abstract : This thesis deals with grating-coupled surface-emitting semiconductor lasers. The work is part of a larger effort that aims at developing semiconductor lasers with built-in beam-forming elements, which eliminate the need for external micro-optics. READ MORE

5. Nonresonant high-frequency actuation of carbon based nanoelectromechanical oscillators
Abstract : Carbon based nanoelectromechanical oscillators outperform their predecessors in many ways. In particular, their extraordinarily high quality factors make them very promising for sensor applications. To operate the nano oscillators, different kinds of actuation mechanisms are utilised, for instance direct or parametric resonance. READ MORE
