Latest Patents

One of his latest patents is the "Structure of Vertical Cavity Surface Emitting Laser." This invention features a structure that includes an ion-implanted region with a gas-furnace configuration arranged in the second mirror layer around a laser light output window. This design allows for several conductive passages between the inner and outer rims of the ion-implanted region, enabling the aperture of the inner rim of the metal layer to be expanded without loss of resistance. This innovation not only eliminates shading effects but also preserves spectrum width suppression functions and improves various photoelectric characteristics, including transmission eye diagrams and photoelectric curve linearity. Additionally, it optimizes high-speed transmission characteristics.

Another significant patent is the "Chip Array Structure for Laser Diodes and Packaging Device for the Same." This invention describes a chip array structure for laser diodes formed on the active surface of a semiconductor chip. It includes multiple light-emitting elements arranged in an array, insulation walls, wire bond areas, and connection electrodes. The insulation walls separate the light-emitting elements into distinct districts, while the wire bond areas are positioned relative to these districts. This design allows for independent electrodes and electrical isolation between the light-emitting districts.
