鉺離子佈植波導之特性研究與應用

Abstract

在單根掺鉺波導放大器(EDWA)中，我們研究單根波導之不同長度及不同激發雷射能量產生不同之淨增益，並讓該掺鉺波導在不同的長度範圍與數種激發雷射能量的比較下，分析其可產生最大增益之長度。我們也將其放入分波多工系統中分析其在不同的波長與激發能量之間的關係並整理增益與雜訊指數之平坦度。 在2 x 2掺鉺多模干涉波導實驗方面，我們將一個2 × 2通道的多模干涉脊狀波導藉由離子植入法將鉺離子打入波導中，並以1550nm可調雷射、準直鏡、單模光纖與光頻譜儀建構成之對光系統去量測其信號之變化，並研究結合掺鉺平面光波導放大器與分波多工元件之可行性。In single erbium doped waveguide amplifier (EDWA), we research single waveguide of various lengths and pump power to produce different net gain and compare with different ranges of length and pump power to get the maximum gain at length. We also insert EDWA into WDM system to analyze the performance between various wavelengths and pump powers and analyze the flatness of gain and noise figure. In experiment of 2x2 Erbium doped MMI waveguide, we implanted the ion of erbium into the 2x2 Multimode Interference (MMI) waveguide by ion implantation, and with 1550nm tunable laser, collimater, single mode fiber and optical spectrum analyzer (OSA) is formed an alignment system to measure and examine the change of output signal, and we study the feasibility of combining erbium doped waveguide optical amplifier and WDM element.
