Abstract

Infrared-transmissive hollow waveguides (HWGs) are enjoying resurgence as they are now being used in lengths less than 10 m for sensor and power delivery applications. HWGs are routinely fabricated with losses less than 1 dB/m from 2 to 12 μm. Most of the hollow structures involve silica or plastic tubing with an inside thin metallic film followed by a dielectric coating to enhance the reflectivity. In this paper current HWG technologies will be reviewed and several sensor and power delivery applications discussed.
