Latest Patents
Dinghs' latest patents include innovative methods for creating semiconductor lasers with end zones designed to reduce non-radiating recombination. The first patent describes a semiconductor laser that features mirror faces serving as resonators. In this design, the active laser region includes end zones adjoining the mirror faces, which are implanted with ions, preferably protons, to create associated crystal damage. The end zones are engineered to have a length that is at least equal to the diffusion length of the recombining charge carriers. This design ensures that non-radiating recombination is minimized at the mirror faces, thereby preventing mirror erosion. The second patent elaborates on a method for forming these end zones through ion bombardment on the upper surface of the semiconductor wafer, which is strategically grooved to facilitate the process.
