“…Nevertheless, the SOP (or the change in SOP) is a parameter often sought measured since it may carry crucial information about the composition and structure of the medium that the wave has been interacting with. As prominent applications, we mention remote sensing within astronomy [1], biology [2], and camouflage technology [3], but also more nascent applications, such as for the fundamental understanding of processes in laser fusion or within the field of quantum communication, advantageously exploit the knowledge of the SOP [4]. Overall, it transpires that polarimetry is of utmost importance in both fundamental and applied science.…”

The state of polarization (SOP) is an inherent property of the vectorial nature of light and a crucial parameter in a wide range of remote sensing applications. Nevertheless, the SOP is rather cumbersome to probe experimentally, as conventional detectors only respond to the intensity of the light, hence loosing the phase information between orthogonal vector components. In this work, we propose a new type of polarimeter that is compact and well-suited for in-plane optical circuitry, while allowing for immediate determination of the SOP through simultaneous retrieval of the associated Stokes parameters. The polarimeter is based on plasmonic phase-gradient birefringent metasurfaces that facilitate normal incident light to launch in-plane photonic waveguide modes propagating in six predefined directions with the coupling efficiencies providing a direct measure of the incident SOP. The functionality and accuracy of the polarimeter, which essentially is an all-polarization sensitive waveguide metacoupler, is confirmed through full-wave simulations at the operation wavelength of 1.55 µm. * alp@iti.sdu.dk 1 arXiv:1607.02013v1 [physics.optics]

“…Metamaterials are subwavelength structures that have recently enabled many new optical applications with a more compact form factor than traditional counterparts . With the reduced feature sizes and scaling of these novel optical devices, many applications will achieve higher performance if nanostructures with a high damage threshold to handle high optical powers can be created.…”

“…Taking advantage of the abundant resonances generated from nanostructures composed of different materials, such as metallic, dielectric, and 2D materials, various kinds of metasurfaces have been proposed in the applications of electromagnetically induced transparency, zero‐index responses, asymmetric spin‐orbit interaction, structural colors, surface waves, topological photonics, and so on. Metasurfaces are also a sophisticated and versatile tool to control optical amplitude, phase, polarization, and the combination of these optical dimensions . Compared with single‐layer metasurfaces, few‐layer metasurfaces with two or more overlapping structure layers significantly increase the effective light–matter interaction distances and exploit the integrated functionalities of metasurfaces .…”

investigated at different wavebands, such as microwave, [1] terahertz, [2,3] and infrared [4] regions. Artificial metasurfaces composed of customized planar nanostructures have been a research hot spot to manipulate EM waves, which provide a wide platform for deep light-matter interactions at the subwavelength scale. [5][6][7][8][9][10] Taking advantage of the abundant resonances generated from nanostructures composed of different materials, such as metallic, [11] dielectric, [12,13] and 2D materials, [14] various kinds of metasurfaces have been proposed in the applications of electromagnetically induced transparency, [15] zero-index responses, [16,17] asymmetric spin-orbit interaction, [18,19] structural colors, [20][21][22][23] surface waves, [24] topological photonics, [25,26] and so on. Metasurfaces are also a sophisticated and versatile tool to control optical amplitude, [27] phase, [28] polarization, [29] and the combination of these optical dimensions. [30][31][32][33] Compared with single-layer metasurfaces, few-layer metasurfaces with two or more overlapping structure layers significantly increase the effective light-matter interaction distances and exploit the integrated functionalities of metasurfaces. [34][35][36][37][38][39] However, to date the integration of arbitrary optical functionalities onto one single metasurface is still challenging due to the limitation of theoretical design and the absence of full control for multidimensional optical fields.Recently, integrated multifunctional metasurfaces that can deal with concurrent tasks have drawn much attention of the scientific community. [40][41][42][43] One of the designs to realize multifunctional metasurfaces is to divide the device into several areas, and each area serves as one functionality. [44,45] Such designs usually suffer from low information capacity and strong noises originated from channels mixing. [46] Another design utilizes harmonic analysis to distribute all the functionality channels to each nanostructures, which has been widely investigated to achieve polarization-controllable multichannel vortex beams generation. [47][48][49] Jiang et al. proposed a broadband multipole vortex beams generation for centimeter waves, and opened up the possibilities for multichannel informational gigahertz modulation. [50] However, the abovementioned designs employ intensity-or phase-only manipulation to control the optical fields, which suffer from unavoidable noises for multifunctional optical devices. Especially for the phase-only design, [51] one usually needs to perform complex optimizations Compact integrated multifunctional metasurface that can deal with concurrent tasks represent one of the most profound research fields in modern optics. Such integration is expected to have a striking impact on minimized optical systems in applications such as optical communication and computation. However, arbitrary multifunctional spin-selective design with precise energy configuration in each channel is still a challenge, and suffers from intrinsic noise...
