Title: The Innovations of Peter Marschall

Introduction

Peter Marschall is a notable inventor based in Neu-Ulm, Germany. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on innovative laser designs that enhance performance and efficiency.

Latest Patents

Marschall's latest patents include a mushroom-shaped semiconductor stripe laser. This invention features a unique design with transversal, monomode light distribution and a double heterostructure. The structure consists of a substrate, a laser-active zone, a cover layer, and an electrically contacting metal layer. The cover layer is underetched to form a mushroom shape, which constricts the laser-active zone to a stripe-shaped region. The ratio of the cover layer's width to the laser-active zone's width ranges from two to five, ensuring effective electrical conductivity.

Another significant patent is an improved semiconductor laser. This device is composed of a sequence of semiconductor layers forming a heterostructure diode. It includes a homogeneously doped layer that defines the laser active zone, with a laser radiation exit face perpendicular to the layers. The design incorporates two differently doped semiconductor layers on opposite sides of the active zone, along with a monocrystalline outer layer. A trough-shaped recess is formed in the outer surface, which helps to lower the series resistance of the laser.
