We study quarter-wave plates, which are typically made out of uniaxial crystals. Depending on its thickness, either a zero-order or a multi-order waveplate can be obtained. A multi-order waveplate is more sensitive to the variation of wavelength, in comparison to a zero-order waveplate. We demonstrate this effect.

A waveplate, made out of optically anisotropic materials, is an optical device that manipulates the polarization of light propagating through it. For example, a quarter-wave plate converts linearly polarized light into circularly polarized light and vice versa; a half-wave plate changes the polarization direction of linearly polarized light. We demonstrate simulations of light propagation through the two types of waveplates in the software VirtualLabTM.

The thin element approximation (TEA) approach is an efficient algorithm to analyze microstructured interfaces, but it is only valid under the condition of paraxial illumination. We hereby develop an extended algorithm to include parabasal illumination, which is characterized by a low divergence with arbitrary propagation direction. In this report, we present such algorithm and compare the results with that of a rigorous calculation in order to demonstrate its validity.
