Title: Innovations of Cheng-Ta Chen in Laser Technology

Introduction

Cheng-Ta Chen is a notable inventor based in Taichung, Taiwan. He has made significant contributions to the field of laser technology, particularly through his innovative patent related to vertical-cavity surface-emitting lasers (VCSELs). His work exemplifies the intersection of engineering and practical application in modern technology.

Latest Patents

Cheng-Ta Chen holds a patent for a "Packaging assembly for high-speed vertical-cavity surface-emitting laser." This invention primarily involves a lens assembly composed of several prisms designed to split a laser beam emitted by a VCSEL element. The design allows a small portion of the laser beam to be directed back to a monitor photodiode (MPD), while the remainder travels along the optical axis. This innovative lens assembly not only alleviates the VCSEL element from being positioned directly under the optical axis but also minimizes signal loss by shortening the length of the bonding wire for the corresponding pin. By positioning the VCSEL element closer to the pin, the design significantly improves the issue of light reflection from a lens or translucent plate on a cap.
