… have used transformation optics to design a universal multimode waveguide star crossing to …

… In this section we design a waveguide crossing for orthogonal waveguides. When the
waveguides cross each other orthogonally, there is no need for the wavefront to bend 45and go …

… crossing medium for waveguides with different core materials. We apply quasi-conformal
transformation optics (QCTO) to transform … }}_3}{{\rm{N}}_4}$ and Si waveguides. The designed …

… intersections of optical waveguides, either a resonator or a mode expander type crossing
device … a new type of waveguide crossing that can channel the light propagation throughout the …

… Here we propose a compact multimode waveguide bend supporting four TE modes simply
by shape-optimizing with transformation optics. The shape of the waveguide is optimized in …

… To overcome this issue, we apply quasi-conformal transformation optics (QCTO) to flatten
one side of the lens and, accordingly, increase the refractive index at this side of the lens. A 1. …

… the mode leakage of waveguide crossings. In this article, a square Maxwell’s fish-eye lens
as a waveguide crossing medium based on quasiconformal transformation optics is designed …

… Within the C-band operation, our waveguide crossing is very efficient with simulations …
port-count optical switching fabrics [20], where a large number of waveguide crossings are needed…

… An interesting solution to manipulate the refractive index called artificial boundary conformal
mapping (ABCM) has been proposed for the design of a waveguide crossing 47 . This …
