“…In addition, the absorption rate, defined as a ratio between the power delivered to the InGaAsSb block and the accepted power to the antenna, is calculated depending on the polarization states of the incident waves. Compared to 3.71% absorption rate at 180 THz for the vertical polarization case, a significantly higher absorption rate of 25.88% is achieved for the RHCP case, which is much higher than the efficiencies (8.58% ∼ 13.7%) from a spiral-shaped structure which guides the CP incident wave to a central aperture [16]. These results demonstrate that the designed cross-tapered bowtie antenna coupled with the InGaAsSb is capable of efficiently sensing the RHCP feature of the incident wave near 180 THz.…”

“…With the liquid crystal polymer, polarizing focal plane arrays were constructed and the arrays were placed on top of image sensors to form full Stokes imaging polarimeters in the visible to IR range [3], [11]- [15]. Also, engineered birefringent materials such as sub-wavelength dielectrics or metal grating structures have been studied for realizing CP-sensitive devices [10], [16]- [22].…”

We propose a novel cross bowtie antenna using phase-shift lines to realize circular polarization (CP) in the infrared (IR) spectrum. The CP antenna consists of a vertical, a horizontal antenna, and two elliptical loops connecting adjacent tips of the antennas to create a 90 • phase shift. The phase-shift lines are conceived to realize a single terminal of the antenna where a detecting material can be mounted and enable the detecting material to fully utilize the field enhancement from the antenna. In full-wave simulations, a nanometer-scale low-bandgap semiconductor, i.e., indium gallium arsenide antimonide (InGaAsSb) capable of detecting IR wave is loaded at the antenna terminal and the antenna structure is designed to achieve CP absorption at 180 THz. The antenna includes a transmission line-based impedance matching structure to compensate for the reactance of the InGaAsSb semiconductor load. To verify the CP detection of the antenna near 180 THz, we numerically show a higher field enhancement value and absorption rate in the antenna terminal in a specific CP case when the antenna is illuminated with incident waves with various polarization states. Also, we design 2 × 1 and 2 × 2 antenna arrays using the CP antennas connected with metallic traces and show that the CP absorption at 180 THz is maintained. Finally, an illustration of a focal plane array based on the proposed CP cross bowtie antennas coupled with the InGaAsSb for a full Stokes polarimeter is presented.INDEX TERMS Infrared antenna, nanoantenna, circularly polarized antenna, stokes vector, infrared full Stokes polarimetry.

“…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.

“…Our IPM design, which is detailed in Section 2, allows many of the limitations of conventional spectropolarimetry methods to be overcome. Moreover, due to its compact size our IPM device allows for direct on-camera integration [37,38,41,42]. In Section 3 we describe the fabrication process of our IPM device which is fully compatible with today's semiconductor manufacturing technologies, before detailing its characterisation over the wavelength range of 500-700 nm in Section 4.…”

Plasmonic metasurfaces enable simultaneous control of the phase, momentum, amplitude and polarisation of light and hence promise great utility in realisation of compact photonic devices. In this paper, we demonstrate a novel chip-scale device suitable for simultaneous polarisation and spectral measurements through use of six integrated plasmonic metasurfaces (IPMs), which diffract light with a given polarisation state and spectral component into well-defined spatial domains. Full calibration and characterisation of our device is presented, whereby good spectral resolution and polarisation accuracy over a wavelength range of 500-700 nm is shown. Functionality of our device in a Müller matrix modality is demonstrated through determination of the polarisation properties of a commercially available variable waveplate. Our proposed IPM is robust, compact and can be fabricated with a single photolithography step, promising many applications in polarisation imaging, quantum communication and quantitative sensing.
