Abstract
Ultracompact polarization components modeled and analyzed with Finite Difference Time Domain Photonics Simulation Software (FTDT) are: a wire-grid linear polarizer and a quarter waveplate for infrared (IR) domain. They will be integrated into a polarization state analyzer (PSA). The components will be manufactured with metamaterials (MTMs). These are composite materials consisting of artificial meta-atoms, i.e. conductive nano- or micro-structures regularly arranged in a dielectric or semiconductor matrix. These conductive structures are made-up smaller than the wavelength of the radiation work. MTMs show extraordinary electromagnetic properties, typically not found in nature, such as negative refractive index. They increase the interaction between radiation and matter. The use of optical polarization components in IR imaging systems dedicated to difficult conditions of visibility is a must, as it allows improving performance and reducing the dimension of optoelectronic devices used in air, car and naval navigation. We will focus on developing the components for applications of imaging polarimetry in long-wave infrared (LWIR) range.
