Abstract

A narrow-band electro-optically tunable infrared filter is described and initial experimental results are reported. The filter is basically a multiple-cavity Fabry-Perot filter. Metal layers, which separate the cavities, serve as electrodes and optically decouple the two or more cavities. The structure has potentially high transmission and may be tuned over a wide range of wavelengths.
