Abstract

A waveguide polarization rotator is provided as unitary body with a first bore; a diametral first septum of the unitary body extending between sidewalls of the first bore. The first septum is twisted between a first end of the first septum and a second end of the first septum. The waveguide polarization rotator may be further provided in a matrix configuration with a plurality of second bores each with a diametral second septum of the unitary body extending between sidewalls of the second bores; a longitudinal axis of the first bore and each of the second bores parallel to one another. The waveguide polarization rotator may be manufactured via injection molding, casting or the like.
