Broadband Modulator Converting Infrared Radiation to Visible Light Based on Resonant Excitation of Surface Waves

The fundamental possibility of developing one of the modulator circuits, i.e., the infrared-to-visible radiation converter, is considered, and its sensitivity is roughly estimated. The problem of visualization of infrared radiation is a relevant subject of study. The scheme of the light-controlled modulator we propose does not replicate any known scheme. Its operation is based on the effect of excitation of a surface plasmon wave.
