本論文探討電吸收調變器於光電與電光轉換之應用，包括電吸收調變器結合天線無線傳輸之架構。文中先探討分散式回饋雷射直接調變數位電視訊號後，以光偵測器或電吸收調變器接收的差別。接著，將電吸收調變器所接收到之數位電視訊號透過實驗室製天線發射，由另一實驗室製天線接收至電視螢幕與電頻譜分析儀，分析電吸收調變器之光轉電特性。然後分析整合電吸收調變器與天線特性，利用兩天線做短距離(10公分與1公尺)無線傳輸，測量數位電視訊號之訊號品質與訊號強度。當天線相距10公分，而注入光功率為-1dBm時，電吸收調變器偏壓在-0.5V~-1V間，訊號品質在65%~77%間，訊號強度在67%左右；兩天線距離增為1公尺，訊號品質與訊號強度約下降10%。當兩天線相距10公分，而偏壓固定為-1V，注入光功率在-8dBm以上時，訊號品質大於61%，訊號強度大於58%，兩天線距離增為1公尺，則訊號品質大於35%訊號強度大於41%，若注入光功率為-3dBm，則訊號品質與強度約達57%。最後，探討電吸收調變器電光轉換與調變DVB-T訊號之光傳輸，使用分散式回饋雷射光源，並利本校實驗室製天線所接收之數位電視訊號經低雜訊放大器後，來調變電吸收調變器，當輸入至電吸收調變器之光功率為-22dBm， 偏壓在-0.3V~-0.5V時有最好訊號品質58%，而訊號強度在此操作範圍內約為68%。

In this thesis, the applications of both the electro-optic and the opto-electronic transformation properties of electro-absorption modulator (EAM) are studied, including the combined subsystem of an electro-absorption modulator (EAM) and antennas.
Firstly, the DFB laser is directly modulated with the digital video broadcasting-terrestrial (DVB-T) signal, which is then detected by two devices, a photo detector or an EAM. Their performances are compared. Next, the DVB-T signal detected by the EAM is re-radiated by a laboratory-made antenna and received by another antenna. A short-distance wireless transmission is studied. Results measured by an electronic spectrum analyzer and a monitor are compared. When the distance between the antennas is 10 cm and the EAM reverse bias varies from -0.5 V to -1 V, the received signal qualities and signal intensities are, respectively, from 65 % to 77 % and around 67 % for the input light power of -1 dBm. At a distance of 1 m, the received signal quality and signal intensity decrease by about 10 %. When the distance between the antennas is 10 cm and the reverse bias is fixed at -1 V, the received signal quality is above 61 % and signal intensity above 58 % for an input light power of -8 dBm. At a distance of 1 m, the received signal quality is above 35 % and signal intensity above 41%. If the input light power is -3 dBm, the received signal quality and signal intensity can reach 57 %.
Finally, the electro-optic transformation property of the EAM is studied through the use of a DFB laser, a LNA, and the DVB-T signal received by a laboratory-made antenna. When the input light power is -22 dBm, the received signal quality and the signal intensity can reach 58 % and 68 %, respectively.
