Study of the characteristics of a polarization-controlled beam after transmission through different nanostructures
type: Dataset
description: In this work, we studied the interaction between light with well-defined polarization and two subwavelength structures milled through an opaque metallic film by using the « Mueller matrix » method. In a first part, we showed that a subwavelength annular concentric slit array, milled completely through the film, allows the filtering and conversion of the incident polarization,generating a radial polarization after transmission. We also showed that it was possible to generate non-diffracting J0 or J2 Bessel beams through such structures and to control their helicity by changing the circular polarization either in preparation or in analysis. In a second part, we showed the creation of a plasmonic bull’s eye structure having the same properties as a quarter wave-plate, by acting on the ellipticities of the rings - to generate a plasmonic phase - and of the central hole - to compensate the strong dichroïsm induced by the differential surface plasmon absorption.
