Title: Innovations of Jyh-Shyang Wang
Introduction
Jyh-Shyang Wang is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly in the development of vertical-cavity surface-emitting lasers (VCSELs) and edge-emitting lasers. With a total of 3 patents to his name, his work has advanced the capabilities of laser technology.
Latest Patents
One of his latest patents is focused on a fabrication method for VCSELs. This method involves forming a contact electrode on a VCSEL within a resonance cavity. A heavily doped layer is created in the resonance cavity where the light intensity is at its weakest. The process includes etching a Bragg reflector while ensuring the etching stop point is above the heavily doped layer. This innovative approach allows for the formation of a contact electrode on the VCSEL structure without requiring high etching precision.
Another notable patent is for an edge-emitting laser that produces a circular beam. This invention utilizes a low-carrier-mobility diluted nitride semiconductor material for the epitaxy light-emitting layer. The use of this material significantly suppresses surface recombination of carriers. The epitaxy structure consists of multiple layers, including a bottom cladding layer, a bottom waveguide layer, a light-emitting layer, an upper waveguide layer, an upper cladding layer, and an electrode contact layer. The light-emitting layer is specifically formed from a diluted nitride material, enhancing the overall performance of the laser.
