Abstract
The thesis discusses theory and the measurement of fiber optic devices employed in multimode network. In particular, an effectively nonreciprocal, multimode coupler has been studied. Development of such asymmetric coupler is required for implementation of passive linear bus, a very attractive topology of a fiber optic network. In the research presented in this work first the theoretical bases of effective nonreciprocal behaviour of fiber optic devices were developed. Next, a nonreciprocal coupler has been build and measured. Subsequently, a new measurement technique and, more significantly, component characterization method for fiber optic devices have been proposed. This method of characterizing multimode fiber optic components is of particular importance in modal dependent networks such as the one described. With many modal dependent devices in the same system, theoretical and experimental description of the performance of the network is missing. Each of the passive and active components of the system must be characterized in a way that would allow for network evaluation. The new modal dependent, nonreciprocal coupler was characterized this way, giving insights into details of its complex performance. Other fiber optic devices (sensors, modulators) have been proposed, built and measured. Finally, the multimode fiber optic system study has been suggested as the complete tool of describing the behaviour of complex fiber optic networks or systems.
