本論文提出一種基於雙層式多層感知器 (2-layer Multilayer Perceptron， 2-layer MLP) 架構之「全光相位與強度調制器」，本架構由定向耦合器、光放大器與光相位調制器所組成。本研究透過4×4轉換矩陣與2-layer MLP架構，利用反矩陣演算法逆向求解系統參數，加上改變定向耦合器之耦合比、光放大器之小訊號增益、相位調制器之項位延遲等參數，並以此為基礎設計出四種功能的調制器，包括：倍角相位、半角相位、強度調制以及簡化版倍角調制器。 第一種，倍角相位調制，本研究透過優化耦合比、放大器的小訊號增益與相位延遲等參數，成功達成輸出相位為輸入相位兩倍之效果。模擬結果顯示，其相位標準差低於 0.006 rad，且功率標準差控制在 0.012 mW 以下，整體模擬後之線性程度高。 第二種，半角相位調制，輸出相位為輸入相位之二分之一。模擬結果顯示，其相位標準差可低於 0.0011 rad，功率標準差則低於 0.008 mW，線性度亦高。 第三種，強度調制，輸入雷射為穩定1mW，經調制後可控制輸出功率隨輸入相位呈現線性增加，由0 W增加至1 mW，經模擬驗證，其功率標準差低於 0.052 mW，成功實現了訊號強度隨相位穩定增加之功能。 第四種，簡化相位調制器，本研究嘗試建構簡化架構之倍角相位調制器，目的為探索降低硬體複雜度之可行性。結果顯示其相位標準差約為 0.73 rad，功率標準差為 0.16 mW，本結果驗證了雙層式多層感知器架構中元件數量與調制精度之關聯性，可作為未來積體光學晶片設計時取捨硬體資源與功能精度之參考依據。;This thesis proposes a phase-controlled phase and intensity modulator based on a Two-layer Multi-Layer Perceptron (2-layer MLP) architecture. The proposed system comprises optical couplers， optical amplifiers， and phase modulators. By employing a 4×4 transfer matrix and the 2-layer MLP framework， an inverse matrix algorithm is utilized to reversely extract the system parameters. Furthermore， by dynamically adjusting the coefficients including the coupling ratios， the small-signal gains， and the phase delays. We designed four modulators including the double-angle phase modulator， the half-angle phase modulator， the intensity modulator， and a simplified double-angle phase modulator. First， the phase doubling modulation， this study optimizes parameters including coupling ratios， small-signal gains， and phase delays to successfully achieve an output phase that is twice the input phase. Simulation results demonstrate high linearity， with a phase standard deviation lower than 0.006 rad and a power standard deviation controlled below 0.012 mW. Second， the phase halving modulation， the output phase corresponds to half of the input phase. Simulation results indicate that the phase standard deviation is less than 0.0011 rad， and the power standard deviation is below 0.008 mW， exhibiting excellent linearity. Third， the intensity modulation， a stable 1 mW input laser is modulated to control the output power， which increases linearly from 0 W to 1 mW with respect to the input phase. Simulations verify an intensity standard deviation lower than 0.052 mW， successfully realizing the function of stable phase-to-intensity conversion. Last， this study attempts to construct a simplified phase doubling modulator to explore the feasibility of reducing hardware complexity. The results show a phase standard deviation of approximately 0.73 rad and an intensity standard deviation of 0.16 mW. It lacks practical applicability due to its high standard deviation.
