| 摘要 |
Embodiments of the invention provide high power waveguide polarizers with broad bandwidth and low loss, and methods of making and using the same. Under one aspect of the present invention, a waveguide polarizer includes a hollow waveguide body having an interior surface; a first ridge disposed on the interior surface of the hollow waveguide body and having an inward-facing surface; and a first plurality of projections disposed on the inward-facing surface of the first ridge. The projections may have a width that is narrower than that of the ridge, and a length that is tunable. The length of the projections may be selected to induce about a 90-degree phase delay in a first mode propagating in a plane parallel to the first ridge relative to a second mode propagating in a plane perpendicular to the first ridge. |
