Optical Polarization Response of Hybrid Gratings Made of Metals and Polymers Based on Bruggeman Theory

Abstract

In the current state of the art of grating designs, compositions involving different metals and polymers have not been adequately addressed. Our study aims to fill this gap by investigating the influence of varying material compositions on polarization properties. To address this issue, we computed the refractive indices of mixtures of gold, silver, and poly(dimethyl siloxane) (PDMS) using the Bruggeman Theory, and simulated optical transmission and reflection of the gratings made of these hybrids. Our analysis revealed prominent peaks in the extinction coefficient at distinct wavelengths for various material ratios. Notably, our simulation results suggest the potential for fine-tuning the extinction coefficient within the range of 450-1000 nm. Furthermore, we demonstrate the attainment of polarization ratios of both 0 and 1 within the simulation environment. These outcomes offer the prospect of designing optical filters and polarizers targeted to specific wavelengths.

Öz

Mevcut literatürde ızgara tasarımlarının farklı metaller ve polimerler içeren kompozisyonları yeterince ele alınmamıştır. Çalışmamız, değişen malzeme kompozisyonlarının polarizasyon özellikleri üzerindeki etkisini araştırarak bu boşluğu doldurmayı amaçlamaktadır. Bu sorunu ele almak için, Bruggeman Teorisi'ni kullanarak altın, gümüş ve poli(dimetil siloksan) (PDMS) karışımlarının kırılma indisleri hesaplanmış, bu melez malzemelerden yapılan ızgaraların optik geçirgenliği ve yansıması simüle edilmiştir. Analizimiz, çeşitli malzeme oranları için farklı dalga boylarında polarizasyon oranında belirgin tepe noktaları ortaya koymuştur. Özellikle, simülasyon sonuçlarımız, polarizasyon oranının 450-1000 nm aralığında ayarlanması potansiyelini göstermektedir. Dahası, simülasyon ortamında hem 0 hem de 1 polarizasyon oranlarına ulaşılabildiği gösterilmiştir. Bu sonuçlar, belirli dalga boylarını hedefleyen optik filtreler ve polarizörler tasarlanmasına olanak sağlayacaktır.
