Abstract: This thesis reports a novel integrated photonic framework for nonlinear and quantum photonic signal processing, using platforms compatible with current standard fabrication processes in microelectronics (also referred to as CMOS compatible where CMOS stands for complementary metal-oxide semiconductors). This is achieved by the proper design of integrated photonic devices enabling efficient interconnections between disaggregated nodes in a network processing information. For this purpose, developing ultra-high-speed interconnects along with efficient quantum interconnects are indispensable for semi-classical and quantum regimes, respectively. This thesis demonstrates a novel approach in designing the optical microresonator for efficient wideband optical frequency comb generation on a chip based on foundry compatible platforms, study the relevant emerging physics in such platform, and extends the idea toward a novel entangled photon state generation in optical and microwave wavelengths for efficient quantum interconnecting purposes. In addition, integrated photonic building blocks for the interaction of photon and atom, i.e., very high-Q miniaturize optical microresonator and efficient input-output couplings at the near-visible wavelength, are demonstrated.
