    摘要: 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.

    摘要: A VCSEL has an active layer, a photodetector in one of the DBR gratings and with a radiation-absorbing layer that is arranged in an antinode of a laser mode. The laser and the photodetector are electrically driven by a common contact on a thick, heavily doped spacer layer that ensures low laser impedance and little electrical crosstalk between the laser and the photodetector.

    摘要: Methods and apparatuses include operating a semiconductor component using a DC/DC-converter. The DC/DC-converter has its duty cycle controlled. A voltage at the semiconductor component is sensed for a voltage. The duty cycle is controlled or regulated so that the sensed voltage corresponds to a predetermined voltage. The predetermined voltage may be gradually increased until a difference between the sensed voltage and the predetermined voltage reaches a predetermined limit.

    摘要: A method for producing an emission module having at least two vertically emitting lasers in which an optically active laser layer is arranged on a substrate and at least one upper covering layer is arranged on said laser layer. In a first etching step, upper mesa regions are formed by etching the upper covering layer, wherein the etching depth of the first etching step is chosen such that the first etching step is ended above the optically active laser layer, and the first etching step is carried out such that the resulting distance between adjacent upper mesa regions is so small that the radiation generated by the finished lasers can be coupled directly into a single optical waveguide. In a second etching step, the optically active layer is severed to form lower mesa regions, the second etching step being a wet-chemical or dry-chemical etching step with a predominantly chemical etching component.
