摘要

本論文致力於超高重覆率的光脈衝序列之產生，與其在毫米波無線通訊上的應用。利用一個光脈衝塑形器對一個31GHz的外調式光頻梳進行逐線塑形，我們成功地產生重覆率可調範圍31-496GHz的1皮秒短脈衝序列，同時我們也利用實驗證明僅用一個逐線脈衝塑形器就能將上述超高重覆率脈衝傳遞至25-km單模光纖之外，而無需使用任何色散補償機制。利用以上光源我們產生高功率的100GHz毫米波載波訊號，並成功達成世界紀錄的20Gbit/s的超高速無線資料傳輸。

This thesis reports the generation of ultra-high repetition-rate optical pulse trains and its applications in wireless millimeter-wave communications. Applying line-by-line optical pulse shaping on an externally-modulated CW laser frequency comb, we are able to experimentally generate 1-ps optical pulse trains with tunable repetition-rates within 31~496 GHz. We also demonstrate the delivery of these ultrahigh rate pulse over 25 km standard single-mode optical fiber without the need for additional dispersion compensating means. Using our approach, we successfully generated remote 100 GHz millimeter-wave carrier signal and enabled world-record 20 Gb/s wireless millimeter-wave data transmission experiments.
