Abstract

The invention relates to the fabrication of modules consisting of a number of light-emitting elements (10) and the associated driver electronics (11) integrated on a common conductive p-type Gallium Arsenide substrate (12). The use of a number of such modules to form in a recording head an uninterrupted row of light-emitting elements is furthermore disclosed.
