21. Time and Frequency Transfer using Passive Techniques in Active Fiber Optic Networks
Sammanfattning : For the modern society, high precision time and frequency transfer have become crucial since a large number of systems, such as telecommunication systems, require precise and stable synchronization. Electric power companies use synchronized systems for taking stability measurements and searching for errors in their networks. LÄS MER
22. Poled fiber devices
Sammanfattning : The topic of this thesis is the development of devices for telecom applications based on poled optical fibers. The focus is on a specific function, optical switching/modulation. Some of the most important results are summarized below. Optical switching at telecom wavelengths (1. LÄS MER
23. Components based on optical fibers with internal electrodes
Sammanfattning : The topic of this thesis is development ofdevices fortelecom applications based on poled optical fibers. The focusis on two different specific functions, wavelength conversionand optical switching.Optical switching is demonstrated in a poled optical fiberat telecom wavelengths (~1.55 mm). LÄS MER
24. Phase-Contrast and Spectroscopic X-ray Imaging for Paperboard Quality Assurance
Sammanfattning : The end-use performance of a paperboard depends on its quality.The major properties of a good quality paperboard include consistencyin the expected ratio between the thickness of the core andthe coating layers, and the uniformity in the coating layer. LÄS MER
25. Modelling and Reliability Assessment of Microsystem Interconnections
Sammanfattning : With the continuous increase of packaging density, the electronic component size and, in particular, the thickness of the involved interconnections decrease significantly. In addition, the microsystem interconnects usually include even finer internal structures. LÄS MER
