Strip-loaded nano-photonics on horizontal slot waveguide

Journal of the European Optical Society-Rapid Publications, 2019
Background A strip-loaded slot waveguide is a waveguide platform allowing a large amount of degrees of freedom in terms of fabrication. Contrary to other waveguide types where the guiding layer has to be patterned, only the shape of the top layer ...

Coupling between multimode fibers and slab waveguides

Optics Express, 2018
In guided-wave optics, using gratings to couple between single mode waveguides and single mode fibers and vice versa is well-established. In contrast, the coupling between multimode waveguides is more complex and a much less understood topic, even though multimode coupling is essential for the excitation of guided modes from spatially incoherent ...

Dual-Band Notch Filter Based on Twist Split Ring Resonators

International Journal of Antennas and Propagation, 2014
A novel dual-band rectangular waveguide notch filter is experimentally investigated in this paper. Such filter is realized by integrating two pairs of split ring resonators (SRRs) printed on the two sides of a dielectric slab with twist angles and ...

3-D-Printed Two-Dielectric Rectangular Waveguide TE₁₀–TE₂₀ Mode Converter

IEEE Access
In this work a novel TE10–TE20 mode converter for rectangular waveguide (RW) is presented. The proposed structure is conceived as a device that can be inserted in an empty straight section of a RW to yield the desired mode conversion.
