Abstract:	本論文以微波光子通信系統(microwave photonic communication systems)中的Radio-over-Fiber (RoF)系統應用為主，使用近彈道單載子光檢測器(near-ballistic uni-traveling-carrier photodiode, NBUTC-PD)此高速寬頻且可供光電轉換效果之主動積體元件與被動電路整合，實現出具有超高速無線傳輸功能之毫米波發射器。為設計高速無線傳輸系統之發射端，於論文中提出NBUTC-PD之等效電路，以模擬方式即提供光電轉換與中頻響應之準確預測，提升設計效率與節省成本；將上述與射頻扼流器(RF-choke)、W頻帶帶通濾波器(W-band bandpass filter)、平面電路至導波管(Waveguide)轉接器及號角天線(Horn Antenna)等被動電路元件整合，設計並實作出光子積體傳輸器(integrated photonic transmitter)；文中亦以上述電路改良後，提出新式射頻扼流器提供元件良好散熱與提升中頻響應頻寬，有效將數位訊號無線傳輸速率提高至20 Gbit/s。　In this thesis, an integrated photonic transmitter front-end is demonstrated. In essence, the front-end circuit consists of an RF-choke, a W-band bandpass filter, an uni-planar slotline-to-waveguide transition, and a W-band horn antenna. The front-end is built with a near-ballistic uni-traveling-carrier photodiode (NBUTC-PD), which exhibits an extremely broadband bandwidth as well as an ultra-wide optical-to-electrical response. It is shown that the NBUTC-PD with proper integrated front-end circuits can find applications in the Radio-over-Fiber (RoF) system for ultra-high-speed wireless data transmission. 　This thesis also presents equivalent circuits to further simplify the system design procedures. The equivalent circuit of the entire system leads to reasonably accurate W-band optical-to-electrical response and intermediate frequency (IF) modulated bandwidth. For experimental demonstration, the proposed front-end is integrated with NBUTC-PD through flip-chip bonding for realization of a W-band integrated photonic transmitter. Since the wide optical-to-electrical bandwidth (35 GHz) as well as broad IF modulated bandwidth (25 GHz), the proposed photonic transmitter is of a high data rate up to 20 Gbit/s and expected to find applications in the broadband wireless-over-fiber system.
