Cost-Effective Polymeric Sulfur-Based IR Wire Grid Polarizer with High optical Performance |
| 초록 |
Inverse-vulcanized polymeric sulfur has a great potential for a low-cost manufacturing of mid-wavelength infrared (MWIR, 3-5 μm) optics owing to its high IR transmittance. Herein, we demonstrate nanostructured gold-coated polymeric sulfur for MWIR wire-grid polarizer with high transmission of transverse magnetic field (TTM) and high extinction ratio (ER). To avoid a trial-and-error approach, a numerical simulation is conducted prior to experiments in order to discover effective polarizer geometries using Fabry-Perot resonance. Then, we investigate various experimental parameters for thermal nanoimprinting lithography (NIL) including pressure, temperature, and time for highly defined periodic nanostructures by filling the nanomold with Wenzel state. In particular, the spacer thickness of the wire-grid polarizer, where the Fabry-Perot resonance occurs, is tailored ranging from nm-scale to μm-scale to enhance the TTM and the ER, simultaneously. |
