中文摘要 | 光纖通訊分波多工系統(Wavelength Division Multiplexing;WDM)中,以陣列波導光柵(Arrayed Waveguide Gratings;AWG)型式的被動元件最具實用性以及發展空間。本論文在於如何設計一個光纖通訊被動元件中的AWG分波多工器,並以基本設計流程完成一個規格為 頻道、400GHz的AWG分波多工器,最後使具有良好的元件分波性能。並詳細介紹AWG元件的設計原理,且使用光波導數值模擬軟體BeamPROP來輔助完成設計的元件。在AWG的自由耦合區域的輸出端與接收端波導上加上錐形口設計(Taper),可使頻道訊號平坦化,並可控制溫度和偏振態對於訊號波長的影響,有效地容許波長漂移的誤差。另外,當AWG錐形口的寬度越大時,頻道寬度也成線性增加,最佳區域分配中錐形口波導每增加1μm寬度,頻道寬度也可以增加0.065nm。此外,本論文研究分析錐形口區域分配對系統的傳輸效率的評比,可以做為在製程上和成本上的參考依據。 |
英文摘要 | Arrayed waveguide grating(AWG) of the passive devices is the most potential and developmental device in wavelength division multiplexing(WDM). This paper is focus on designing AWG in optical fiber communication and building a basic design of channel, 400GHZ AWG which have good performance. Further, expound AWG’s principle completely and utilize BeamPROP to design component. Adding taper structure to AWG I/O waveguide of free propagation range(FPR), the spectrum response becomes flat and the error of wavelength shift which is influenced by temperature and polarization is tolerated. In addition, as the width of taper is increased by 1μm, the width of spectrum response is also increased by 0.065nm.The propagation effectiveness of taper structure can be a standard of fabrication and cost. |
