2. Reconfigurable and transparent wavelength division multiplexed optical transport networks
Sammanfattning : This thesis is about reconfigurable and transparentwavelength division multiplexed (WDM) networks.Reconfigurability is used to achieve higher surveillance andthroughput in the network. This is done by wavelength selectiveand independent network elements. These network elements canaccomplish bypass and protection switching ofthe traffic. LÄS MER
3. Heterogeneous material integration for MEMS
Sammanfattning : This thesis describes heterogeneous integration methods for the fabrication of microelectromechanical systems (MEMS). Most MEMS devices reuse the fabrication techniques that are found in the microelectronics integrated circuit industry. This limits the selection of materials and processes that are feasible for the realization of MEMS devices. LÄS MER
4. Applications of monolithic fiber interferometers and actively controlled fibers
Sammanfattning : The objective of this thesis was to develop applications of monolithic fiber devices and actively controlled fibers. A special twin-core fiber known as a ‘Gemini’ fiber was used to construct equal arm-length fiber interferometers, impervious to temperature and mechanical perturbations. LÄS MER
