Method for building silicon-based coupling resonance loop structure capable of providing stimulated Raman scattering light grain

Abstract

The invention relates to a method for building a silicon-based coupling resonance loop structure capable of providing stimulated Raman scattering light grain. The method comprises the following four steps of: 1, making a required silicon on insulator (SOI) substrate on the surface of common pure single-crystal silicon by an ion implantation method; 2, building the silicon-based coupling resonanceloop geometrical light path structure capable of providing the stimulated Raman scattering optical grain on the SOI substrate; 3, building a silicon-based SOI ridge waveguide on the geometrical lightpath structure; and 4, respectively arranging a p+ doped area and an n+ doped area at the left side and the right side of the silicon-base ridge waveguide to form pn junction, and continuously performing a simulated Raman process to generate light grain. By Raman light grain, the loss of transmission light in the structure can be effectively compensated, and the signal-to-noise ratio of the Ramanoptical grain serving as an optical waveguide gyro can be improved. Therefore, by the method, an integrated optical waveguide gyro with high sensitivity can be obtained. Moreover, the method has better practical values and wide application prospects in the technical field of integration of an optical gyro coupling resonance loop.

However, in the process of scientific experiments and engineering implementation, due to the material properties (such as light absorption and scattering, etc.) and structural characteristics (such as bending radius light loss, etc.) Seriously affect the performance of the coupling resonator ring as the core component of the optical waveguide gyroscope, so that the existence of optical loss makes the optical waveguide gyroscope have no advantage compared with the traditional fiber optic gyroscope under the condition of given loss and size
