Abstract

We propose waveguide structures which transform an incident unpolarized beam into a polarized microbeam and also can be used as spin-flippers by varying the incidence angle on the structure. We describe optimized structures combining these functions. Such waveguides could be used for the investigation of one-dimensional magnetic structures and could be implemented on any existing fixed wavelength reflectometer.
