Achromatic angle-insensitive infrared quarter-wave retarder based on total internal reflection at the Si-SiO2 interface.
An achromatic infrared (lambda = 1.2-4 microm), Si-prism quarter-wave retarder (QWR) is described that uses total internal reflection at a buried Si-SiO2 interface at an angle of incidence phi near 33 degrees, where deltaDelta/deltaphi = 0. The retardance delta deviates from 90 degrees by < +/- 2 degrees within a field of view of +/- 10 degrees (in air) over the entire bandwidth. Because the Si...
متن کاملUV-SWIR Achromatic Quarter Wave Retarder for the Multiangle Spectropolarimetric Imager (MSPI)
We describe the design, fabrication, and testing of an achromatic, athermalized quarterwave retarder, a key component for the Multiangle Spectro-Polarimetric Imager (MSPI), which is a candidate for the Aerosol-Cloud-Ecosystem (ACE) mission. The desired wavelength range of the instrument encompasses the UV, visible, near IR, and shortwave IR, extending from 355 nm to 2130 nm, with polarimetric c...
متن کاملTerahertz achromatic quarter-wave plate.
Phase retarders usually present a strong frequency dependence. We discuss the design and characterization of a terahertz achromatic quarter-wave plate. This wave plate is made from six birefringent quartz plates precisely designed and stacked together. Phase retardation has been measured over the whole terahertz range by terahertz polarimetry. This achromatic wave plate demonstrates a huge freq...
متن کاملA subwavelength slit as a quarter-wave retarder.
We have experimentally studied the polarization-dependent transmission properties of a nanoslit in a gold film as a function of its width. The slit exhibits strong birefringence and dichroism. We find, surprisingly, that the transmission of the polarization parallel to the slit only disappears when the slit is much narrower than half a wavelength, while the transmission of the perpendicular com...
متن کاملTesting of Reflective Quarter-Wave Retarder in EUV Range
There has been an increasing demand to understand the optical, electronic, and structure properties of materials at shorter wavelengths in the far ultraviolet (FUV) and extreme ultraviolet (EUV) range. This has pushed researchers to examine and outline new optical devices as quarter wave retarder (QWR) which, coupled with other techniques, can provide valuable information about physical and opt...
