摘要

光電混頻器在微波-光纖系統扮演相當重要的角色，因其不需要昂貴複雜的鎖相LO信號，只需利用中心節點的光LO信號，就可以輕鬆達到發射與接收端同步的目的，因此在本論文中我們提出藉由覆晶技術結合近彈道傳輸單載子光檢測器，與共平面波導耦合線濾波器之光電混頻器，利用該光檢測器特有之非線性特性結合帶通濾波器，我們可以同時達到低的內部轉換損耗(4.3dB)、與高的調制頻寬(>10GHz)。

The optoelectronic mixer plays an important role in radio-over-fiber system due to the LO signal of emitter and receiver can be simply synchronized through optical LO signal from base station without expensive and complex phase-lock electrical LO signal. Therefore, we demonstrated an optoelectronic mixer by binding the near-ballistic uni-traveling-carrier photodiode (BUTC-PD) and planar coupled line filter together through flip-chip assembly technology. Low internal up-conversion loss as low as 4.3dB, and wide up-conversion bandwidth (>10GHz) have been achieved simultaneously.
