Title: Innovations of Cheng-Ju Wu

Introduction

Cheng-Ju Wu is a notable inventor based in Zhubei, Taiwan. He has made significant contributions to the field of laser technology, holding a total of four patents. His work focuses on enhancing the performance and efficiency of edge-emitting lasers.

Latest Patents

One of his latest patents is for an edge-emitting laser having a small vertical emitting angle. This innovative design includes an upper cladding layer, a lower cladding layer, and an active region layer sandwiched between the two cladding layers. By embedding a passive waveguide layer within the lower cladding layer, an extended lower cladding layer is formed between the passive waveguide layer and the active region layer. The refractive index of the passive waveguide layer is larger than that of the extended lower cladding layer. This configuration allows the passive waveguide layer to guide the light field downward, expanding the near-field distribution of the laser light field in the resonant cavity. As a result, this design achieves a smaller vertical emitting angle in the far-field laser light field.
