6. Additive Manufacturing and Integration of 3D MEMS using Ultrafast Lasers and Magnetic Assembly
Sammanfattning : The geometry of MEMS devices is limited by the technologies used to fabricate them. Today, microsystems are manufactured with patterning technologies that allow only for 2D and 2.5D geometries. LÄS MER
7. Monocrystalline-Silicon Based RF MEMS Devices
Sammanfattning : This thesis presents novel radio-frequency microelectromechanical (RF MEMS) devices, for microwave and millimeter wave applications, designed for process robustness and operational reliability using monocrystalline silicon as structural material. Two families of RF MEMS devices are proposed. LÄS MER
8. Integration of diffractive, refractive and plasmonic optical structures in highly functional MEMS-based scanning and biosensing systems
Sammanfattning : .... LÄS MER
9. Photonic MEMS for optical information technologies
Sammanfattning : Photonic integrated circuits (PICs) combine hundreds of optical components on a chip, and can enable fast communications, high-performance computing, and improved sensing. PICs, made by miniaturized optical waveguides, require many reconfigurable elements to enable programmable functionalities and to compensate for fabrication variations and environmental factors.
