Paper Abstract

In this project we design and fabricate a hyperbolic metamaterials-based narrowband notch filter for the mid-wave infrared regime with an angle-of-incidence independent center-wavelength for TM polarized incident light. To achieve angle of incidence independence, a subwavelength sized array of copper wires is inserted in a vertical orientation and permeates the three middle layers of the seven layer Bragg stack filter. Analysis using Maxwell- Garnett theory and full-wave electromagnetic modeling, and the fabrication progress to date are presented. Narrowband notch filters have applications in optical communications systems, and remote sensors such as hyperspectral and multi-spectral sensing and imaging.
