Paper Abstract

Polarimetric sensing has been shown to have numerous applications in imaging such as enhancing the contrast of an image and the shape of the source object. There is increasing interest in developing a sensor that is able to measure all the Stokes parameters of an incident beam without a reduction in image resolution. We propose a cavity array metasurface polarization sensor capable of determining the complete elliptical polarization state of an incident beam allowing for the Stokes parameters to be calculated within a single pixel. The metasurface consists of a metal lm with periodically patterned cavities lled with an absorbing dielectric. Each unit cell of the periodic array contains three di erent cavities with each cavity interacting in a di erent manner with the incoming beam, absorbing the radiation. The absorption in each of the three cavities depends on the incident polarization state and phase of the incident beam. An isolated measurement of the absorption in each cavity within the unit cell is possible with separate collection of photogenerated carriers. This will enable the elliptical polarization state of an incident beam to be measured. In this work, we describe the elements of the metasurface sensor and numerically characterize its optical response to elliptically polarized light.
