Title: Tomi Leinonen: Innovator in Vertical Cavity Surface-Emitting Lasers
Introduction
Tomi Leinonen is a notable inventor based in Zurich, Switzerland. He has made significant contributions to the field of vertical cavity surface-emitting lasers (VCSELs). With a total of two patents to his name, Leinonen's work focuses on improving the performance and reliability of these devices.
Latest Patents
Leinonen's latest patents revolve around the concept of oxide aperture shaping in VCSELs. His innovative approach involves a corrected mesa structure that compensates for variations in the shape of the created oxide aperture resulting from anisotropic oxidation. Specifically, he derives a corrected mesa shape by determining the shape of an as-created aperture formed by oxidizing a circular mesa structure. He then ascertains the compensation required to convert the as-created shape into a desired target-shaped aperture opening. This compensation value is utilized to modify the shape of the mesa itself, ensuring that subsequent anisotropic oxidation yields a target-shaped oxide aperture.
