Abstract
A bricked sub-wavelength periodic waveguide and a modal adapter, power divider and polarization splitter that use the waveguide. The waveguide includes blocks disposed periodically with a period 'L' on a substrate and which alternate with a covering material. The first blocks have a width “a” and the second blocks have a width “b”, alternating on the substrate according to a period “L” the second blocks being shifted a distance “d” the first blocks in the direction of propagation. A modal adapter, a power divider and a polarization splitter all use the periodic waveguide and can operate with larger wave periods without leaving the sub-wavelength regime.
