本論文探討於用戶端以低成本光源做為光網路架構的傳輸光源，採用C波帶垂直共振腔面射型雷射直接調變數位電視地面廣播訊號於被動光網路中傳輸，並且以此光源注入鎖模法布理-比洛雷射二極體，直接調變1.25Gbps數據資料上行傳輸，再搭配L波帶可調式雷射調變10Gbps數據資料下行傳輸，達到單線雙向被動光網路。文中實驗C波帶垂直共振腔面射型雷射於4公里單模光纖與1公里多模光纖傳輸之應用，分析不同光纖下訊號品質的特性變化。在不影響數位電視訊號品質的情況下，分光注入鎖模法布理-比洛雷射二極體，直接調變1.25Gbps、2^7-1虛擬隨機序列NRZ碼為上行訊號，L波帶下行訊號調變10Gbps、2^31-1虛擬隨機序列NRZ碼，上下行訊號單線雙向傳輸25公里單模光纖，數位電視訊號品質可維持在40%以上，上下行25公里單模光纖數據資料接收光功率靈敏度分別為-22.58dBm與-20.2dBm。同時，文中也實驗分析討論垂直共振腔面射型雷射注入鎖模條件與光功率的限制。

In this thesis, a low-cost passive optical network using the Fébry-Perot laser diode (FP-LD) injection locked by Vertical Cavity Surface-Emitting Laser(VSCEL) is presented. It can broadcast DVB-T signals and bidirectional transmit high-speed data using injection-locked technique. Moreover, results of remodulation experiment with injected light carrying radio signal are shown. Experimental results are shown for the simultaneous transmission of DVB-T broadcasting signal over 4-km single-mode fiber (SMF) and 1-km multi-mode fiber (MMF), upstream 1.25 Gbps NRZ data using a C-band VCSEL, and downstream 10 Gbps NRZ data using a L-band laser diode. Maintaining the TV signal quality at 40%, bidirectional transmission sensitivity of -20.2 dBm and -22.58 dBm are shown for the downstream and upstream over 25-km SMF. Furthermore, the constraint of injection-locked and the limitation of optical power are also analyzed experimentally.
