| dc.description.abstract | 在本篇論文中，我們使用近彈道單載子傳輸光二極體(Near Ballistic Uni-traveling-carrier Photodiode, NBUTC-PD)基底的光子傳送混波器(Photonic Transmitter-Mixer, PTM)展示了一個遠端分發及升頻的20Gbps無線振幅調變資料傳輸於W-頻段(75-110GHz)。這種新元件由一個主動的近彈道單載子傳輸光二極體與平面、積體化的被動電路組成。這些被動電路被設計來饋入中頻(intermediate-frequency,IF)調變輸入信號及萃取出寬頻的光電輸出信號。藉由發展出精確的疊加式分析模型，以及將頻帶相異的信號分離到不同的路徑，中頻調變輸入信號及光電輸出信號可被精準的設計以及分別地進行最佳化。於是我們可以同時達成超寬的光電轉換頻寬(67-118GHz)以及中頻調變頻寬(>15GHz)，並在近彈道單載子傳輸光二極體與WR-10波導管輸出端之間擁有低入射損耗(<2dB)，同時在中頻調變時擁有高明滅比(33dB)。藉由使用這種高品質元件，無誤碼(error-free)的遠端升頻20Gbs無線振幅調變資料傳輸獲得了成功。在另一方面，我們也發展了一個遠端分發的1皮秒(pico second, ps)光脈衝列做為無線資料傳輸所需的同步高品質光子載波，其重複率為93GHz。這種信號由光譜逐線塑形器透過重複率倍增(repetition rate multiplication, RRM)產生。相較於傳統的93GHz正弦載波，同電流下其相應的毫米波功率要高上4dB。不同於高損耗的頻域振幅濾波，我們用來產生93GHz脈衝列的的重複性倍增技術是基於在31-GHz光頻梳上應用週期性無耗損頻域相位濾波。不同於傳統的鎖模雷射，在長途傳輸中所造成的光纖色散可以被完全地預先補償而不需要額外的色散補償組件。在我們的實驗中，整個無線傳輸連結提供超過15GHz的基頻頻寬用以傳輸超寬頻資料。由於近彈道單載子傳輸光二極體的高功率表現以及所使用的高速毫米波偵測器所具有的高感測度，在展示的無線連結中無論發送端或接收端都沒有使用毫米波放大器。因此，我們展示了遠端分發及升頻的20Gbps無線振幅調變資料傳輸，並在通過25公里長標準單模光纖(standard-single-mode-fiber,SSMF)後依然能成功地維持無誤碼。

| dc.description.abstract | In this thesis, we demonstrated a remotely up-converted and distributed 20Gbit/s wireless on-off-keying (OOK) data transmission link at W-band by using near-ballistic uni-traveling-carrier photodiode based photonic transmitter-mixer (NBUTC-PD PTM). Such novel device is consisted of an active NBUTC-PD and integrated planar passive circuit for both feeding intermediate-frequency (IF) modulation input and extracting wide-band optical-to-electrical (OE) output signals. By developing an accurate analytical model in a cascade topology and separating signals in different operating bands into different flow paths, the OE output and IF modulation input responses can be designed precisely and optimized respectively. Accordingly, we can achieve both ultra-wide OE bandwidth (67-118 GHz) and IF modulation bandwidth (>15GHz). Moreover, a low coupling loss (<2dB) at W-band from NBUTC-PD to WR-10 waveguide output port and a high extinction ratio (>33dB) during IF modulation can be also achieved simultaneously. By use of such high-performance device, 20Gbit/s on-off keying (OOK) error-free wireless data transmission can be achieved successfully under remotely up-converted scheme. On the other side, we also developed a remotely distributed 1ps optical pulse train source with a repetition rate at 93GHz as high performance synchronized photonic carrier for wireless data transmission. It is generated by a spectral line-by-line shaper with the repetition rate multiplication (RRM) technique. As compared to conventional 93GHz sinusoidal carrier, the corresponded millimeter wave (MMW) power of this carrier is 4dB higher under the same output photocurrent from PD. In contrast to the lossy amplitude filtering, our RRM technique for the 93 GHz pulse train is based on applying periodic loss-less spectral phase filtering onto the 31 GHz comb lines. In contrast to the traditional mode-locked laser, the fiber dispersion for a long-reach transmission distance can be totally pre-compensated without additional dispersion compensation components. In our experiment, the entire wireless link (after up/down-conversion process and a pair of horn antenna) provides a >15GHz baseband bandwidth for transmitting ultra-broadband data signal. Thanks to the high power performance of NBUTC-PD and high sensitivity of adopted high speed MMW detector, the W-band MMW amplifiers are eliminated in both transmitting and receiving ends of our demonstrated link. Consequently, a remotely distributed and up-converted 20Gbit/s error-free OOK wireless data transmission link over 25km standard-single-mode-fiber (SSMF) has been demonstrated successfully.
