New paper in Optics Express – Diffraction gratings generating orders with selective states of polarization
We published a new paper in Optics Express. The paper, entitled «Diffraction gratings generating orders with selective states of polarization» appears in the second issue of the journal in 2016.
In this paper we propose specially designed double anisotropic polarization diffraction gratings capable of producing a selective number of diffraction orders and with selective different states of polarization. Different polarization diffraction gratings are demonstrated, including linear polarization with horizontal, vertical and ± 45° orientations, and circular R and L polarization outputs. When illuminated with an arbitrary state of polarization, the system acts as a complete polarimeter where the intensities of the diffraction orders allow measurement of the Stokes parameters with a single shot. Experimental proof-of-concept is presented using a parallel-aligned liquid crystal display operating in a double pass architecture.
