- 요약Silicon nitride has become a widely used material platform for photonic integrated circuits owing to its broad optical transparency window (400 nm - 2.5 μm), relatively high refractive index, widely accessible growth mechanism in CMOS foundries, and ability to achieve low propagation losses. In this dissertation, we discuss the efforts to achieve high laser spectral purity based on high-Q silicon nitride waveguide resonators, nonlinear Brillouin dynamics, and low-noise coil waveguide reference resonators for laser stabilization. The first part focuses on the design and fabrication of low-confinement silicon nitride waveguide resonators with 200 - 700 million intrinsic Qs. Based on the low-loss waveguides, the Brillouin scattering laser using both the higher-order Stokes suppression approach and large mode volume coil resonator approach achieves fundamental linewidths of 77 mHz and 30 mHz, respectively. Enabled by the low-loss silicon nitride platform and its design and fabrication advantages, we developed a scalable integrated optics solution for optical reference resonators for laser stabilization using 8-inch-CMOS-fabricated and 300-million-intrinsic-Q coil waveguide resonators with low thermal noise limits including 4-m, 10-m, and 17-m long coil waveguide resonators. This dissertation concludes with the development and demonstration of a fully stabilized narrow linewidth Brillouin laser with a Brillouin laser, power splitter, coil resonator resonator on one chip, realizing a Hz-level fundamental linewidth and a 70 Hz integral linewidth. These results show great potential of silicon nitride based integrated optical reference resonator and laser technology in visible and near-infrared wavelengths for a broad range of applications such as coherence communications, low-noise microwave generation, fiber sensing, quantum photonics and atomic, molecular and optical (AMO) applications.
