Abstract: Abstract We report results of polarimetric observations of comet 21P/Giacobini-Zinner made at phase angles, α ≈ 76–78°, between 10 and 17 of September 2018, and compare them with previous measurements. We find significant variations in the polarimetric… read more here.

Abstract: Metasurfaces are a new class of diffractive optical elements with subwavelength elements whose behavior can be lithographically tailored. By leveraging form birefringence, metasurfaces can serve as multifunctional freespace polarization optics. Metasurface gratings are novel, to… read more here.

Abstract: Short-wave infrared (SWIR) imaging polarimetry has widespread applications in telecommunication, medical imaging, surveillance, remote-sensing, and industrial metrology. In this work, we design, fabricate, and test an achromatic SWIR elliptical polarizer, which is a key component… read more here.

Abstract: Metasurfaces-subwavelength arrays of phase-shifting elements-present new possibilities for polarization optics and polarimetry. In particular, a periodic, polarization-sensitive metasurface diffraction grating can enable full-Stokes imaging polarimetry with a single polarization-sensitive component. In this work, we show… read more here.
