本論文主要探討平面光波導電路(Planar Light Circuit)半導體雷射耦合問題，目前半導體雷射耦合一般需要人工對位，成本高、費時、誤差率高。如果能使耦合組裝的結構能利用機械上對位或是能在架構上能夠用一體成形的方法，就能讓耦合的誤差降低及傳輸效率提高。
本論文提出兩種架構之研究，由雷射光源發射經過特殊設計的斜面反射後，進入光纖光通道裡，其過程針對材料選擇、角度分析、光線追蹤做了一詳細之研究，並擇一架構加入了聚光透鏡(micro lens) 可使聚光效果增加，測量其架構的傳輸效能。最後把光線發散角(divergent angle)角度收斂在理想數值範圍內，以利後端未來研究使用。
在這裡我們使用三種不同直徑的雷射去測量傳輸效能及其誤差，由於在架構上無法確定實際上雷射光源發射器的位置，所以我們做了光源發射器的位置對於光通量的誤差分析，在這部份分析中，光源發射器位置誤差範圍內皆可有良好的傳輸效率。
此系統可使光通訊雷射耦合端的耦合效率提高 ，對於後續的光通訊元件能有更好傳輸效能。

This thesis focuses on the coupling of semiconductor laser into planar light circuit. As of today, a semiconductor laser coupler usually requires manual alignment. This alignment method yields higher cost, longer time, and higher rate of error. If we can use mechanical counterpoint to the coupling structure or integrates components into one piece structure, we can reduce the coupling error and increase the efficiency of transmission.
This paper presents two architectures. With a reflection slope, the laser light enters the fiber optical channel. By using ray tracing, we analyze the coupling efficiency and the angular profile pattern for different structure material. A micro lens is added to enhance the coupling efficiency.
The effect of aperture diameters on the transmission efficiency for these two types of structure is studied. The intensity distribution as a function of the laser position is analyzed to optimize the coupling efficiency. This research provides an efficient method to couple the laser diode light source into a light channel.
