“…The flexibility in tuning metasurface functionality through their structure can also bypass the reliance on special material properties, such as birefringence [15,28]. Metasurfaces consequently represent an opportunity for polarimetry to overcome unwieldy and expensive architectures [29][30][31][32][33][34][35][36], but implementations so far have suffered from parasitic losses, low efficiency, or a need for digital data processing. Some designs also partially negate the size advantage of metasurfaces by requiring detection of light in the far field.…”

In-line polarimeters perform nondestructive polarization measurements of optical signals, and play a critical role in monitoring and controlling the polarization environment in, for example, optical networks. While current in-line polarimeters are constructed with multiple optical components, either fabricated into an optical fiber or using free-space optics, we present here a novel architecture conducive to monolithic on-chip integration. This enables the scalable fabrication of high-performance polarization sensors with exceptional stability, compactness, and speed. The method relies on the detection of the highly polarization-dependent scattered field of a subwavelength antenna array known as a metasurface, and is shown here to provide polarization state measurements matching those of a state-of-the-art commercial polarimeter.

“…Here, early approaches in determining the SOP utilized a combination of a metasurface together with conventional optical elements [9,10] (like polarizers and waveplates), or the effect of polarization-dependent transmission of light through six carefully designed nano-apertures in metal films [11]. Likewise, different types of metasurfaces have been proposed for determination of certain aspects of the SOP, like the degree of linear [12] or circular [13,14] polarization. Recently, however, metasurface-only polarimeters that uniquely identify the SOP have been proposed and verified.…”

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]

“…Metasurfaces have the potential to improve the performance of devices in a variety of applications including lensing [1], beam steering [2], solar energy [3], perfect absorbers [4]- [6], selective emitters [7], [8], and photon sorters [9]- [12]. Metasurfaces are composite films of subwavelength thickness made of a two dimensional array of subwavelength elements or meta-atoms [13].…”

Abstract-We present experimental results demonstrating the spatial sorting of incoming radiation in two spectral ranges. A metasurface composed of a periodically patterned metal of subwavelength thickness with dielectric inclusions concentrates and localizes electromagnetic fields near the surface. Light of the separate spectral bands is channeled into different geometrically tuned cavities within each spatially repeating unit cell. Excitation of cavity modes facilitates this simultaneous spatial and spectral selective absorption. The measured reflection and field profiles are presented and show the spectral and spatial selectivity. A method to apply these concepts to split radiation into three spectral bands is also proposed.
