英文摘要： The mechanism and technology of widely tunable femtosecond optical parametric oscillator based on the ultra-fast four-wave mixing in the silicon waveguide will be investigated in this project. Firstly, the physical mechanism of the femtosecond optical parametric oscillator in the silicon waveguide will be studied systemically from the theoretical standpoint，and the simulation model of the femtosecond optical parametric oscillator in the silicon waveguide will be built. The novel way of optimizing waveguide's multi-parameters achieved single mode propagation will be explored numerically. The key method and technology of broadband phase matching in silicon waveguide will be developed through the management of the dispersion and nonlinearity. Secondly, the key method and technology of the femtosecond optical parametric oscillator based on silicon waveguide, which exhibits a compact configuration with lower threshold and high conversion efficiency, will be investigated experimentally. The femtosecond pulse oscillation in the optical parametric oscillator will be realized using the high nonlinear silicon waveguide as the parametric gain material. Moreover, the dispersion engineering method can be adopted to obtain the generation and stable propagation of the femtosecond pulse in the optical parametric oscillator. Th
