Figure 1
Schematic magnetic design of the EPU. Quadrants 2 and 4 move longitudinally, in and out of the plane of the figure. Moving the quadrants in the same direction (parallel mode) yields elliptically polarized light, while moving them in the opposite direction (antiparallel mode) produces linearly polarized light at varying angles.
