Title: The Innovative Contributions of Jin Kwang Kim
Introduction
Jin Kwang Kim is a prominent inventor based in St. Louis Park, MN (US), known for his significant contributions to the field of vertical cavity surface emitting lasers (VCSELs). With a total of 12 patents to his name, Kim has made remarkable advancements in thermal management and optical confinement structures.
Latest Patents
One of his latest patents, titled "Metal-assisted DBRs for thermal management in VCSELs," describes a VCSEL that includes a substrate with a partially removed portion and a metal-assisted distributed Bragg reflector (DBR). This innovative design features a metal layer located at the substrate's partially removed portion, along with an active region containing multiple quantum wells. The second mirror stack is positioned over the active region, allowing for a reduced number of alternating layers in the first mirror stack compared to traditional VCSELs. This technology is particularly beneficial for long-wavelength VCSELs on InP substrates or red-color VCSELs on GaAs substrates.
Another notable patent is focused on "Long wavelength vertical cavity surface emitting lasers." This invention includes independently definable current and optical confinement structures that enable unique drive current forms and transverse mode confinement. The optical guide can be formed from an upper DBR, an etched mesa structure, or an intracavity optical guide, while the current guide may feature an ion-implanted region within the upper DBR. A dielectric structure surrounds the optical guide, enhancing the overall performance of the VCSEL.
