光子積體電路(photonic integrated circuits，PIC)之整合技術大多僅限於以光路取代傳統電路，而光訊號在傳輸至電子元件前，仍須轉變為電訊號才能進行運算，若想藉由光訊號取代電訊號進行運算，必須先從元件最基本之儲存媒介，即光學式記憶體(optical memory)開始研究。
本論文將藉由電阻記憶體與垂直式環形耦合共振器之整合，開發具有電寫入、光讀取功能之新型光學式記憶體，並做可行性分析。由於電阻式記憶體(ReRAM)具有體積小、低功耗、讀寫速度快等優點，同時元件結構亦是現存記憶體當中最簡單之架構，故相當適合與其他元件做結構上的整合。環形共振器(microdisk resonator)則是因擁有波長選擇特性，且元件製程技術成熟，而成為光子積體電路不可或缺的元件之一。
本論文在研究的過程中共製作了兩個元件，首先是對平行耦合雙圓環共振器進行元件製作，並利用可調變式雷射光源(tunable laser)和極化控制器(polarization controller)，以邊射型耦合(end-fire coupling)的方法將光波耦合至元件中，使得光波於共振條件下被篩選，進而在輸出端之光學頻譜分析儀(OSA)中得到相對應的傳輸頻譜，對元件之光學特性做探討；其次是設計電阻記憶體與垂直式耦合環形共振器(VCMR)之整合元件，此元件承襲環形共振器的光學特性，但改以垂直方式耦合光波，並與電阻式記憶體整合於單一元件上，進而探討元件的光波長選擇、記憶儲存、光物質交互作用等特性，對此元件是否能成為新型光學式記憶體做可行性分析。

The integration technology of photonic integrated circuits (PIC) is mostly limited to replacing traditional circuits with optical equivalents. When the optical signal is transmitted to the electronic component, it must be converted first into an electronic signal before the subsequent operation can be implemented. Before this optical-to-electrical conversion actually takes place, it is important to realize that the success of manipulating and processing the optical signal would inevitably require the help of optical memory devices to store the relevant optical data involved.
In this paper, the plausibility of developing a new type of optical memory with electrical writing and optical reading functions which is constructed by integrating the resistive memory with the vertically-coupled microdisk resonator is duly investigated. Resistive random-access memory (ReRAM) typically has several advantages which include small size, low power consumption, and fast read/write speed. From the structural viewpoint, the component involves the simplest architecture as compared to other existing memory counterparts. Therefore, this simplicity is unique for ReRAM to be viably integrated with other optical components including the microdisk resonator, which is one of the indispensable building blocks of the photonic integrated circuit due to its wavelength selective characteristics and mature component processing technology.
In the course of the research, two device components are fabricated. First, the parallel-coupled double ring resonator is realized. The light wave coming from a tunable laser with a proper polarization control is fed into the waveguide component by the end-fire coupling so that the light wave is selectively filtered under the resonance condition. The corresponding transmission spectrum is obtained from the optical spectrum analyzer (OSA) at the output, and the optical characteristics of the components evaluated are discussed. The second component constructed is a ReRAM-based microdisk resonator which has dual functionality of memory and optical spectral filtering capabilities. Furthermore, the characteristics of selective light wave filtering, memory storage, and the interaction of light with are discussed, in order to assess the applicability of using this dual-function device as a new optical memory in the future.
