description: The object of the study is gallium arsenide with an epitaxial layer doped with a silicon donor impurity and with an integrated waveguide for near-infrared radiation. The aim of this work is to increase the intensity of terahertz radiation from an epitaxial layer of gallium arsenide doped with a silicon donor impurity by emptying the impurity state during stimulated radiative interband recombination of an electron at the impurity level with a hole of the valence band. As a result of this work, photoluminescence spectra in the near-infrared region of the spectrum were obtained and stimulated emission was recorded. The dependence of the integral intensity of terahertz radiation of the structure on the optical pumping power was also investigated. The change in the character of this dependence is associated with the generation of stimulated radiation. Thus, for the first time it was possible to achieve an increase in the intensity of terahertz radiation in GaAs by introducing a waveguide of the near-infrared range into the structure. The results of this work may influence the progress towards the creation of a new type of semiconductor laser source.
