Abstract

In this paper, the numerically efficient finite element based full vectorial modal and propagation approaches are used to design and optimize various photonic components for the manipulation of polarization effects in opto-electronic systems. Designs of directional coupler-based polarization splitters both using a metal cladding and without a metal cladding are presented. It is also shown that a compact polarization splitters both using a metal cladding and without a metal cladding are presented. It is also shown that a compact polarization splitter can be designed by using single section or two-section multimode interference (MMI) guides. In this paper, a novel concept of a single polarization optical waveguide with layered core is introduced and its expected performance is reported, along with its experimental validation. In this paper, the origin of polarization cross-talk and design approaches to minimize its detrimental effects is also presented. Finally, designs of single and multiple sectioned passive polarization rotators using waveguides with slanted side-walls are also presented.
