Photopolarimeter based on planar grating diffraction

Division-of-amplitude photopolarimeter based on conical diffraction from a metallic grating.

Polarizing diffraction-grating triplicators.

We report experimental results with a reflective continuous anisotropic polarizing diffraction-grating beam splitter that produces three diffraction orders. The diffraction efficiencies and polarizations of the diffracted orders are controlled through the incoming polarization state and by use of a wave plate with arbitrary orientation located between the grating and a mirror. In particular, we...

The Diffraction Grating

One-way diffraction grating.

Diffraction gratings are elementary tools for much of optics and spectroscopy. Here, at microwave frequencies, we provide a new perspective on these fundamental structures. A transmission diffraction grating is presented that has diffracted beams emanating from one surface only. It can thus function either as a transmission grating with no reflected orders (other than zero) or, in the reverse c...
