Silicon can be very effectively exploited in integrated optics due to its well-defined process chemistry and the availability of techniques developed primarily for the semiconductor industry which allow control over dimensions and the creation of arbitrary two dimensional structures with great precision and repeatability. In this thesis the complet...

The sharp rise in non-linear loads in the form of electronic devices (and direct current operated electrical appliances), especially in the residential and office sectors, has now led to a situation in which 'distortive reactive currents' (or harmonic currents) arise to a great extent due to pulse-shaped power consumption. In the course of the inve...
