Abstract
The invention relates to a laser diode including a vertical resonator and to a method for producing the laser diode such that at least one active layer is configured between reflective layers. The invention is characterized by configuring at least one antioxidation layer between the reflective layers, thus preventing distortion caused by unintentional oxidation. The antioxidation layer consists of a III–V semiconductor material with a proportion of a molar aluminum of less than 0.7 and/or a III–V semiconductor material with an optical depth of at least two quarter waves.
