NTU-Array之光學連接模組

Abstract

本論文敘述NTU-array光學傳輸模組的設計與製作。NTU-Array是一個無線電天文干涉儀，用來觀測在78-113GHz頻段宇宙背景輻射的SZ效應。藉由觀測SZ效應我們可以了解宇宙結構的演化歷史。第一章簡介干涉儀的架構。第二章描述光學傳輸模的組成元件，包括：增益等化器、二個前級放大器、光發射器、光接收器，以及後級放大器。利用光學傳輸可以有：訊號不會隨著距離的增長，而劇烈地衰減的好處。第三章說明增益等化器的設計公式推導、模擬。第四章交代增益等化器和光學傳輸模組的量測結果。第五章做一總結，以及未來的工作展望。

This thesis focuses on the design and fabrication of the optical link module of NTU-Array. NTU-Array is a microwave interferometer which is made for probing the high red-shift objects by measuring the SZ effect. In Chapter 1, we introduce the scientific goals and a framework of NTU-Array. Chapter 2 and Chapter 3 describe the design and fabrication of optical link module. The benefit of transferring signals by the optical fiber is that the attenuation will not increase dramatically with distance. In Chapter4, we describe the measurement results of the gain equalizer and the optical link module. In Chapter 5, we summarize our work and present a future outlook.
