Abstract

The ability to rotate the polarization of light propagating through a material by applying a magnetic field was discovered by Faraday. It is critically important for applications involving light modulation and sensors. Shaped plasmonic crystals function as miniature polarizers. This study investigates a gold nanorod array that can be used to significantly vary the Faraday effect originating from a dielectric material. The dependence of the Faraday effect on the polarizer angle exhibited well-defined characteristics. The birefringence of the nanorod array was characterized using a simplified setup for optical polarization tomography. The enhanced Faraday effect due to the plasmonic nanorods is promising for applications involving plasmonic circuits and refractometry.
