Abstract

This ph.d. thesis deals with the modelling, fabrication and characterization of photonic bandgap components realized in silicon-on-insulator material. Plane-wave expansion theory and finite-difference time-domain modelling are applied to the photonic crystal waveguide and demonstrate how the fundamental properties of such may be altered in terms of the operational wavelength range, the propagation loss, and the dispersion properties. The inverse design method topology optimization of broadband performance for different passive nanophotonic components. the fabrication of photonic crystals is covered in detail for the utilization of electronic beam lithography and reactive ion etching. photonic crystal structures corrected for proximity effects and with sub-20 nm features are successfully realized and etched with high fidelities and steep wall frofiles into silicon moreover, nanoimprint lithography is demonstrated to be an attractive candidate for the lithographic step in the mass-production of nanophotonic circuits. The thesis presents numerous experimental results on fabricated photonic crystal components including various waveguide bends, T- and Y-splitters, wavelength dependent filters, improved butt-coupling, and slow-light waveguides the results promote the interest of applying photonic bandgap components in nanophotonic circutis that being for simple guiding, splitting, and multiplexing of light or for the utilization of the slow-light phenomenon for non-linear effects or dispersion compensating
