6. Longer Wavelength GaAs-Based VCSELs for Extended-Reach Optical Interconnects
Abstract : Data centers of today are increasing in size and are built to accommodate strong traffic demands while providing sustainably by having clients sharing resources under one roof. Their massive scale puts pressure on the server network topology and has incited a need for data transmission links that are energy efficient and capable of operation at high bit rates with reach up to a few kilometers.

8. Strongly non-linear magnetization dynamics in nano-structures: perturbations, multi-mode generation, and topological droplets
Abstract : Spin torque oscillators (STOs) are magnetic nano-devices in which strongly non-linear magnetodynamic phenomena can be excited by current. In this thesis, we study some of these phenomena by means of micromagnetic simulations, analytical calculations, and electrical characterization. Three main subjects are discussed: 1. READ MORE

9. Carbon-nanotube-based nanoelectromechanics
Abstract : Carbon nanotubes, a novel material with extraordinary mechanical and electrical properties, are good candidates for designing nanoelectromechanical systems. The typical length scale of these systems is nanometers and an important characteristic is a coupling between electrical and mechanical degrees of freedom. READ MORE

10. Quality-Driven Synthesis and Optimization of Embedded Control Systems
Abstract : This thesis addresses several synthesis and optimization issues for embedded control systems. Examples of such systems are automotive and avionics systems in which physical processes are controlled by embedded computers through sensor and actuator interfaces. READ MORE
