    Abstract: 本論文之主要貢獻於利用結合高非線性轉換效率之週期性或非週期性極化反轉鈮酸鋰材料、低損耗光學波導、積體化高速調制電極設計之元件,延承傳統非線性光參量轉換系統,拓展至量子光源系統的開發與研究,本論文收錄之各項研究主題條列如下:。
    ;The major contribution of my thesis is proposed a concept of demonstrating the fully integrated quantum optical circuits from the classical optical parametric down conversion process to the novel quantum approach of adiabatic coupling and entangled photon-pairs generation systems based on a domain-engineered lithium niobate crystals with high electro-optically tunable and modulation ability and corresponded diffused-type waveguide devices. With close teamwork of the R&D and fabrication groups of Professor Chen, Yen-Hung laboratory in National Central University, the member of Polaris photonic Co. Ltd. and the resource of Professor Dragomir Neshev laboratory in Nonlinear Physics Centre, Australian National University for quantum light source qualifications. We demonstrated several systems or devices in 2012-2017, which all have the potential market value. The topics of this thesis are divided to topic I to V as the following:

    Topic Research
    I Electro-optical tunable, multi-wavelength optical parametric generators in aperiodically poled Lithium Niobate.
    II Electro-optically spectrum tailorable intracavity optical parametric oscillator.
    III High-speed Lithium Niobate Electro-optical modulators array.
    IV-1 Ultra-broadband adiabatic light transfer in titanium diffused Lithium
    Niobate waveguides.
    IV-2 Ultra-broadband asymmetric adiabatic coupler for two-photon quantum-polarization state preparation.
    V Experiments of quantum integrated optical circuits.

    In final, we proposed a concept of the fully integrated quantum optical polarization state preparation based on titanium-diffused, domain-engineered lithium niobate waveguide device on the second section of the chapter 6.

    The clear physical mechanism of quantum entanglement is still not yet clear, this universe is in the era of change, for the past, present or future, is the definition of time arrow needed to be redefine? Is the four-dimensional space-time enough to describe the universes? It needs more sustained research and contribution of all successors, the answer may be approached, but maybe, the universe never made it easy for people to get the so-called answers. What we can do is, from personal research to the collective intelligence, so that, we hope we can continue to grow, understand and comprehend “the universe”.
