Title: Innovations of Sergio Pellegrino in Semiconductor Laser Technology
Introduction
Sergio Pellegrino is a notable inventor based in Turin, Italy. He has made significant contributions to the field of semiconductor laser technology, holding 2 patents that showcase his innovative approach to laser design and manufacturing processes.
Latest Patents
One of his latest patents is titled "Semiconductor laser having low current threshold." This invention includes a substrate and mechanisms for reducing lateral current flow, which are composed of at least three layers. The external layers are entirely doped, while the internal layers are doped only in the zones lateral to the active element, effectively minimizing side current flow. Another significant patent is "Process to manufacture laser structures with lateral confinement." This process involves producing a multilayer device that emits coherent luminous radiation when electric power is applied. The device consists of a substrate, a first epitaxial layer, an active layer with a specific composition for desired wavelength emission, and multiple confinement layers. To enhance current flow through the active layer, the adjacent layer is implanted with ions of transition elements, such as Co or Fe, which, after thermal treatment, exhibit high resistivity.
