Title: Innovations of Seongsin Kim in VCSEL Technology
Introduction
Seongsin Kim is a notable inventor based in San Jose, CA, who has made significant contributions to the field of vertical cavity surface emitting lasers (VCSELs). With a total of 2 patents to his name, Kim's work focuses on enhancing the performance and reliability of these advanced optical devices.
Latest Patents
One of Kim's latest patents is titled "Moisture passivated planar index-guided VCSEL." This patent describes systems and methods for passivating planar index-guided oxide vertical cavity surface emitting lasers. The invention addresses the susceptibility of these devices to damage caused by moisture intrusion into the etch holes used to form the index-guiding confinement regions. The VCSEL includes a vertical stack structure with a substantially planar top surface, comprising a top mirror, a bottom mirror, and a cavity region that contains an active light generation region. Notably, at least one of the mirrors has a layer with a peripheral region that is oxidized into an electrical insulator due to exposure to an oxidizing agent. The structure defines multiple etched holes extending from the top surface to the oxidized peripheral region, with each hole being moisture passivated by an overlying moisture penetration barrier.
