Abstract

About 1963, cuprous chloride (CuCl) was found to have a number of advantageous electrooptic characteristics as compared to the KDP family of electrooptic materials: it has a low optical loss over a wide spectral range from the visible through the infrared, a low refractive index and a low dielectric constant as well as a low loss tangent at microwave frequencies. This means that a wider range of infrared frequencies may be modulated (CuCl transmits to 20 microns), greater angular aperture, lower modulating power, and a greater ease of use in both cavity-type and travelling-wave type modulators. Cuprous chloride modulators, requiring only modest input power, have been demonstrated experimentally and operated continuously with band-widths of tens of MHz at microwave frequencies. The major problem hindering its full development and use has been the (difficulty in producing) good strain-free crystals, a problem arising from the phase transformation.
