本論文中，我們提出一種應用在分波多工系統中可能較便宜的頻譜分割的非同調光源代替傳統的雷射光源，以使分波多工系統架構更為簡單與高適應性，但是頻譜分割光源會遭受到放大的自發性發射(amplifier spontaneous emission，ASE)與ASE拍差雜訊的影響，如此一來，就必須將光頻譜變寬或是將電頻譜變窄(改變調變速率)。在本論文中我們在光接收機前使用頻道內的四波混合(intra-channel four wave mixing，IC-FWM)將進入接收機的信號光源變寬，壓抑光源的強度雜訊。結果不僅完成將頻譜分割光源應用在傳輸速率為8 × 2.5 Gb/s頻道間隔為200 GHz的分波多工傳輸系統中，我們也完成頻譜分割光源在光纖光柵為基礎的光塞取多工器與馬可詹德式光纖光柵為基礎的塞取多工器系統中進行光波道塞入和取出的操作與串音現像問題的探討。

In this thesis, we propose a potentially inexpensive light source for the mulit-channel wavelength division multiplexing (WDM) system applications. The spectrum-sliced incoherent light source (SILS) is alternative conventional laser source for the WDM system owing to its simplicity and flexibility. However, the spectrum-sliced source suffers from the intensity noise and spontaneous-spontaneous beat noise. Thus, it is necessary to increase the optical bandwidth or decrease the electrical bandwidth (by varying the bit rate ) to improve the signal to noise ratio (SNR). We used the intra-channel four wave mixing (IC-FWM device) before the receiver to suppresses the intensity noise of the light source, thus greatly expands the optical bandwidth of the received signal. We not only demonstrated the capability of an 8 × 2.5 Gb/s, DWDM with 200 GHz channel spacing transmission system by utilizing only one spectrum-sliced source, but also investigate the cross-talk issue of SILS in the fiber Bragg grating-based optical add/drop multiplexer (FBG-based OADM) and the Mach-Zehnder fiber Bragg grating-based optical add/drop multiplexer (MZ FBG-based OADM) systems.
