Polarisation Discrimination and Surface Sensing with a Near-IR Nanostructured Hybrid Mirror
Posted on 04.08.2022 - 21:33
We demonstrate experimentally how to turn a conventional distributed Bragg reflector into a polarisation selecting mirror operating in the near-IR at normal incidence without diffraction and with high extinction ratio. Our approach involves combining a dielectric multilayer composite with a sub-wavelength metal wire-grid nanograting, which can be routinely fabricated using a number of the existing planar fabrication techniques. Moreover, the design and working principle of our nanostructured hybrid mirror enable it to operate as a surface sensor and allow straightforward integration of the mirror with functional materials for tuning its wavelength/ polarisation extinction ratio.
