Title: Kwang-Kuo Shih: Innovator in Light Emitting Diodes
Introduction
Kwang-Kuo Shih is a prominent inventor based in Chu-Tung Chen, Taiwan. He has made significant contributions to the field of optoelectronics, particularly in the development of high-efficiency light-emitting diodes (LEDs). With a total of 3 patents to his name, Shih's work has had a substantial impact on modern lighting technologies.
Latest Patents
One of his latest patents is for a high-efficiency white light-emitting diode. This invention features a light-emitting diode chip, a transparent substrate, a transparent Ohmic electrode, a reflection layer, and a contact diode, all covered with a submount that includes a conductive trace. The transparent substrate has a rough surface that is positioned on the first surface of the chip, while the transparent Ohmic electrode is placed on the second surface and connected to the contact electrode. The submount, designed for high thermal conductivity, ensures effective heat dissipation. Additionally, the surface of the chip is coated with fluorescent paste, which absorbs some of the emitted light and produces a complementary light, allowing observers to perceive white light.
Another notable patent is for a laser diode intended for digital versatile disks (DVDs) and its fabrication method. This innovation simplifies the manufacturing process by eliminating the need for regrowth steps during the Metal-Organic Chemical Vapor Deposition (MOCVD) process. The laser diode operates with a low threshold current due to its excellent current confinement, and it is constructed from an AlGaInP alloy. A layer of Al,Ga,As is formed between the cladding layers and is oxidized to create a current confinement layer, which also serves as a dielectric layer in the ridge structure.
