A Mid-Infrared Dual-Band Filter With Ultra-High Resolving Power

A Mid-Infrared Dual-Band Filter With Ultra-High Resolving Power

A mid-infrared (mid-IR) dual-band filter with ultra-high resolving power is designed and numerically investigated. It is composed of an Al<sub>2</sub>O<sub>3</sub> layer between a gold grating and a CaF<sub>2</sub> substrate. Each unit cell of the grating consists...
