超平坦光梳頻技術應用於高密度分波多工傳輸系統之研究與設計

本論文使用雙端驅動式馬赫倫德爾強度調變器搭配振盪器在調變器其中一端接上相移器以及衰減器(a由這些元件組成光梳頻產生器作為發射端。接著利用極化控制器對單雙雷射作極化角度的控制，使其正交來降低雷射輸出光信號間的功率疊加及串音的影響。此光梳頻產生技術使一個雷射光源產生十九個通道，其通道間距為0.14nm。最後使用摻鉺光纖放大器作為功率放大器，來提升信號經過光梳頻產生器後所損失之功率。本傳輸架構使用單模光纖搭配色散補償光纖傳輸在C-頻帶位元率為10Gbit/s。再比較非歸零碼歸零碼和載波抑制歸零碼三種調變方式之傳輸效能，最後與二階段串連式調變結構之多波長產生器做比較。高密度分波多工系統)即可能為未來的趨勢，但系統架構之成本與複雜度也會隨著通道數增加而增加。而本模擬研究使用之光梳頻產生技術可大幅降低整個系統架構之成本與複雜度。

The dissertation applies Dual-drive Mach-Zehnder modulator goes with an oscillator and it takes one side of the modulator connects with phase shift and attenuator. The Optical Frequency Comb Generation (OFCG), consists of these components, is used to be transmission launching end.Moreover, it uses Polarization Controller (PC) to control the polarization angle of odd and even lasers, and then makes it orthogonal to diminish the effect of power superposition and crosstalk between lasers light export signals. The OFCG technology makes a laser producing 19 channels, and each channel’s space is 0.14nm. In the end, using an Erbium Doped Fiber Amplifier (EDFA) to be a power amplifier is to enhance the signal power losing after going through OFCG. The transmission structure consists of Single Mode Fiber (SMF), and goes with Dispersion Compensation Fiber (DCF), which the signal transmit is in the C-band and bit rate is 10Gbit/s. Furthermore, three modulation kinds of transmission performance, Nonreturn to Zero (NRZ), Return to Zero (RZ) and Carrier Suppressed Return to Zero (CSRZ), compare with two stage serial type Multi Wavelength Generator (MWG) modulation in structure. Nowadays, high intensive Dense Wavelength Division Multiplexing (DWDM) system with high transmission and long distance assures to become a trend in the future. The cost and complication of the system skeleton.
