We investigate the radiation due to transitions of ballistic electrons in a superlattice. The equations of motion for the populations of photons and electrons are used to analyze the system both as an amplifier and as an oscillator. We then calculate the gain of the system and the threshold current needed to overcome electromagnetic losses. Finally, we compare our proposed infrared active system with other existing lasers.
