摘要:	本論文為第一個提出將20-Gbps高頻傳輸線整合於矽基光學平台，並且應用於板對板光學連接模組之研究。此高頻傳輸線可以作為連接垂直共振腔面射型雷射、光偵測器、發射端驅動積體電路和接收端轉阻放大器等主動元件之間的高頻訊號線。而上述元件將整合於矽基光學平台上，並且透過矽基光學平台上的45矽基光學微反射面將高速光學訊號導入帶狀光纖陣列，成為一個高速板對板光學連接模組。其中面射型雷射與光偵測器的封裝以覆晶接合方式完成，而驅動積體電路及轉阻放大器與傳輸線間則以打線方式連接。為了評估和分析用於矽基光學平台的高頻傳輸線，包含單端訊號式(single-ended)傳輸線與差動訊號式(differential)傳輸線的散射參數(scattering parameters, S-parameters)量測；傳輸線皆以共平面波導(co-planar waveguide, CPW)作為設計型式。單端訊號式傳輸線在操作頻率為50-GHz下，量測之反射損耗約為 -30.5 dB以及插入損耗約為 -0.15 dB。差動訊號式傳輸線在操作頻率為40-GHz下，量測之反射損耗約為 -20.12 dB以及插入損耗約為 -0.28 dB。而板對板光學連接模組整體高頻特性上，量測得到清晰20-Gbps眼圖且接收端誤碼率可達到10-12等級。證實此20-Gbps高頻傳輸線之設計可實際整合於矽基光學平台，並且在板對板光學連接模組應用上更可以達到20-Gbps傳輸等級。 The research of this thesis is first proposed that the 20-Gbps high-frequency transmission line is integrated into silicon optical bench (SiOB), and applied to board-to-board optical interconnect module. The high-frequency transmission line could be high-frequency signal line to connect among active components, like vertical-cavity surface-emitting laser (VCSEL), photo-detector (PD), driver integrated circuit (IC) of transmitter, and transimpedance amplifier (TIA) of receiver. The above components would be integrated into the SiOB to be a high-speed board-to-board optical interconnect module, and the high-speed optical signal would coupled into ribbon fiber via 45° Si-based optical micro-reflector of SiOB. In the packaging approaches, the VCSEL and PD were assembled by flip-chip bonding method and the driver IC and TIA were assembled by wire bonding method to connect with transmission line. In order to evaluate and analyze the characteristics of transmission line, the scattering parameters (S-parameters) of passive circuit with single-ended and differential transmission lines would be measured, respectively. These transmission lines were designed based on the coplanar waveguide structure. The return loss and insertion loss of single-ended transmission line at 50-GHz were -30.5dB and -0.15dB, respectively. The differential transmission line was operated at 40-GHz, which had return loss of -20.12 dB and insertion loss of -0.28 dB. For high-frequency characteristics of board-to-board optical interconnect module, the clear eye diagram is operated with data rate of 20-Gbps and the bit error rate (BER) of receiver can be achieved the level of 10-12. The results are confirmed the design of 20-Gbps high-frequency transmission lines can be integrated into SiOB, and apply to board-to-board optical interconnect module with transmissive level as high as 20-Gbps.
