Polarization Analyzer

Wire-grid polarizers, which can create a linear polarization state of the transmitted light, are a common type of optical element in numerous applications. Due to their structure in the sub-wavelength range, a rigorous treatment of the light propagation is necessary. VirtualLab’s polarization analyzer with its inbuilt RCWA enables the detailed analysis and optimization, not only of polarizers, but also anti-reflection structures and other types of gratings. It provides polarization-dependent information about reflected and/or transmitted diffraction orders, while the efficiency also can be analyzed with respect to the wavelength and/or incident angles.
