Abstract

A photocathode is formed with a first absorber assembly on a first substrate for a first spectral band and a second absorber assembled on a second substrate for a second spectral band. The second substrate is different from the first substrate, and the second spectral band is different from the first spectral band. The first absorber and the second absorber can be joined using a direct semiconductor wafer bonding process. The integration of a second absorber such as an SWIR absorber layer can extend the spectral response of image intensifier tubes.
