Big data is transforming our approach to problems pertaining to fundamental sectors of today's societies such as healthcare, telecommunication, and transportation. To harness the potential in big data, the IT infrastructure must be capable of handling the huge amount of information, and therefore needs innovative solutions in three main areas: transportation, storage, and data processing. With the ever increasing performance of microprocessors, it is clear that copper interconnects are imposing a bottleneck on the data flow due to limited bandwidth, crosstalk, and energy scalability. Therefore, Wavelength-division-multiplexing(WDM)systems based on intra-chip optical interconnects, implemented on silicon-on-insulator (SOI), rise as an excellent candidate to overcome the limitations imposed by copper interconnects. Optical filters serve as a building-block for essential WDM systems component. In this work, an algorithm to synthesize generalized cascaded Mach-Zehnder interferometer lattice filters is developed which would allow the realization of commonly used frequency responses such gain equalizers and wide bandpass filters. The algorithm is then used to synthesize a linear optical discriminator using three different filter architectures. In addition, a dynamic model of silicon microring resonators considering silicon nonlinearities is described. Nonlinear distortions introduced by microring resonator filters to modulated optical pulse trains are studied and their impact on performance of integrated photonic analog-to-digital converters is analyzed. The method is applied to a first-order microring resonator add-drop filter and the effects of nonlinearities are analyzed for different input pulse parameters. Finally, different methods of reconstructing the phase response of microring resonator filters are examined and applied to reconstruct the phase response of a second-order microring resonator add-drop filter from its measured magnitude response. The results are compared to theoretical and experimentally measured phase response.
