The main objective of the dissertation is to present work describing theoretical studies of planar structures with erbium doped regions and characterization of erbium doped particles. Numerical models of erbium doped Al2O3 were formulated, taking into account the up-conversion from the metastable Er3+ levels and the cross-relaxation process as a mechanism of energy transfer between Er3+ ions. The influence of amplified spontaneous emission (ASE) is also fully considered in the numerical model. The first part of this research investigates the effects of design geometries and nonlinear losses...

Current there are no products that provide the flexibility and interoperability required in dynamic assembly and coordination of services, which commonly involve massively distributed components, legacy systems, and diverse technologies. Moreover, none of them fully integrates process logic with decision logic. Nor do they take into account the local autonomies and address the need for distributed decision making in service composition and orchestration. The demand for the system is to deliver demand driven, integrated, and personalized services through dynamic service creation and...
