Title: Innovations by Tzu-Ching Yeh

Introduction

Tzu-Ching Yeh is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of optical technology, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is a packaging assembly for high-speed vertical-cavity surface-emitting laser (VCSEL). This design utilizes a lens assembly made up of several prisms to effectively split a laser beam emitted by a VCSEL element. The assembly guides a portion of the laser beam back to a monitor photodiode (MPD), while allowing the remainder to travel along the optical axis. This innovative design alleviates the VCSEL element from being positioned directly under the optical axis, thereby reducing signal loss by shortening the length of the bonding wire. This improvement significantly enhances the performance by minimizing defects caused by reflections from lenses or translucent plates.

Another significant patent is for a high-speed multi-channel optical transmitter module and the method for fabricating it. This module comprises multiple laser-diode (LD) components, photo-diode (PD) components, an MT ferrule, and a waveguide component. These components are initially packaged as individual sub-modules, which are then combined to create the high-speed multi-channel optical transmitter module. This approach reduces the number of individual components, simplifies the structure, and increases positioning precision. Consequently, this innovation decreases the time and labor required for assembly and packaging, while also enhancing the defect-free rate of the products.
