In integrated photonic circuits, silicon-on-insulator waveguides with different geometries have been employed to realize a variety of components. Therefore, efficient coupling of t…
Controlling branching angle of waveguide splitters based on GRIN lenses
S. Hadi Badri, M. M. Gilarlue, S. G. Gavgani
Designing beam splitting structures with wide branching angles is of great significance. The branching angle of conventional Y-junctions is limited. In this paper, we investigate t…
Photonic crystal waveguide crossing based on transformation optics
M. M. Gilarlue, S. Hadi Badri
The absolute instruments like the Maxwell's fisheye (MFE) lens with aberration-free imaging properties have found interesting applications such as waveguide crossing. The flat wave…
Low-index contrast waveguide bend based on truncated Eaton lens implemented by graded photonic crystals
S. Hadi Badri, M. M. Gilarlue
Low-index contrast waveguides such as silica waveguides are indispensable part of passive integrated optical components. Reducing the bending radius of silica waveguides with low b…
Maxwell's fisheye lens as efficient power coupler between dissimilar photonic crystal waveguides
S. Hadi Badri, M. M. Gilarlue
The imaging properties of the Maxwell's fisheye (MFE) lens makes it a viable candidate to implement power coupling between different types of waveguides. A coupler based on the MFE…
