摘要:	本論文提出以玻璃中介層架構設計用於4通道 × 25-Gbps光連接模組之接收端光學次系統組裝，此光學次系統組裝整合光偵測器、轉阻放大器(TIA)、微透鏡、高分子聚合物波導於玻璃中介層上。其中，光偵測器與轉阻放大器以覆晶封裝法封裝至玻璃中介層一面，兩者之間以高頻傳輸線連接；另一面則以光阻製作微透鏡。光訊號透過高分子聚合物波導的45°反射面轉折進入微透鏡聚焦後，由光偵測器接收。接收端光學次系統的光學量測上，以多模光纖取代光偵測器作初步的評估，系統之耦合光效率最高為37%。在最高光學效率下降1 dB時，光偵測器與光纖接頭的位移容忍度均在 ±10 μm以內，可供未來正式封裝光偵測器於玻璃中介層上之參考依據。高頻傳輸線的設計上，包含單端傳輸線(Single-ended)與差動傳輸線(Differential)之設計，本研究只針對單端傳輸線進行討論。設計的兩組單端傳輸線取樣頻率範圍在1 ~ 62.5 GHz之間，量測之反射損耗都高於20dB，而插入損耗也都有低於1dB，符合25-Gbps設計之標準。 ;In this thesis, the design of a receiver optical sub-assembly for 4 channel × 25-Gbps optical interconnect module using a glass interposer structure is proposed. The photodiode, transimpedance amplifier (TIA), microlens, and polymer waveguide will be integrated on the glass interposer. The PD and TIA are integrated on one side of the glass interposer by using flip-chip packaging, and connecting with each other through the high-frequency transmission lines. The microlens array is fabricated on the other side of glass interposer to converge optical signal reflected by the polymer waveguide’s 45° mirror. The PD is replaced by a core of 50-μm diameter multimode fiber (MMF) to measure optical characteristics in the receiver optical system. The maximum optical coupling efficiency in the optical system is 37%. The alignment tolerance at 1-dB level for PD and MMF is larger than ±10 μm, it can be a reference for integrating PD into glass interposer in the future. The design of high-frequency transmission lines include single-ended and differential transmission lines, but in this research only single-ended transmission lines. The measurement frequency scale is from 1~62.5 GHz, return loss of two different type single-ended transmission lines are higher than 20 dB, and insertion loss are lower than 1 dB.
