Polarization is a fundamental property of light and a key aspect of the modern world, spanning applications from quantum to classical realms, laboratory to industrial, and metrology to meteorology. Commonly, polarization is used as both a measurement tool and an information carrier. To extract the information, one needs to characterize the polarization after the interaction of light with the detecting media. However, the full characterization of polarization is less than trivial, given that polarization is a multi-parametric property. As such, characterizing a polarization in full involves its decomposition into the basis states, a process that typically requires several reconfigurable optical elements and computational reconstruction.

Early study on the Dirac Fermion utilized two-dimensional (2D) systems like graphene, while more recent work on the subject has focused on three-dimensional Dirac semimetals (3D DSM). 3D DSM has a key structural advantage over graphene monolayer in that it shows linear band dispersion with a macroscopic thickness. Similar to graphene, the Dirac band structure of 3D DSM confers very high optical nonlinearities. Since Dirac physics describes charge carriers in both 2D and 3D DSM, 3D DSM should have similar optical properties to graphene, such as tunable optical conductivity, high nonlinear optical coefficients, and stronger light confinement. Also, 3D DSM is better for plasmonic waveguides than 2D graphene because it has a 3D structure, which gives it an extra degree of freedom. Based on these great qualities, 3D DSMs are a good replacement for 2D DSMs. Cadmium arsenide (Cd3As2) is a popular 3D DSM because of its chemical stability in air and exceptional optical properties.
