Title: The Innovative Contributions of Yoichi Shindo
Introduction
Yoichi Shindo is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, particularly in the development of laser diode devices. With a total of nine patents to his name, Shindo's work has had a considerable impact on the industry.
Latest Patents
One of Shindo's latest patents is for a resin-sealed laser diode device. This invention addresses the issue of sealing resin deterioration caused by laser beams. To combat this, a thermosetting rubber-like organic silicone resin layer is applied to the front light-emitting end face of the laser diode chip. This layer is designed to be at least 50 micrometers thick, extending over the active layer's surface. Additionally, the design includes a curved rubber-like organic silicone resin layer on the photo-diode side, which helps maintain the integrity of the laser beam's far field pattern by incorporating silicon dioxide in the end-face protecting film.
Another notable patent is for a semiconductor laser device and its manufacturing method. This device features a laser diode chip mounted on a sub-mount, along with a monitor photo diode for tracking the emitted laser beam. The design includes a metallic main plate that supports both the laser diode chip and the monitor photo diode, as well as an end-face breaking protective layer. A unique aspect of this invention is the space provided at the interface between the protective layer and the seal resin, which is designed to be irradiated with a monitor laser beam at a controlled intensity.
