Abstract

The experimental development of an infrared multiple-cavity electrooptically tuned Fabry-Perot filter using LiNbO₃ is described. This filter, designed for operation in the 3–5-μm spectral band, was demonstrated by angle scanning using a He–Ne laser at 3.39 μm. The multiple-cavity configuration increased the free-spectral range of the 2-Å bandwidth filter from 67 to 670 Å as observed in the increased angular spacing of transmission peaks. Because of the large halfwave voltage of LiNbO₃ at these wavelengths, tuning was restricted to ~15% of the free-spectral range.
