A High Density Integrated Optical Waveguide

Abstract

The invention relates to a high-density integrated optical waveguide. The optical waveguide is arranged on a waveguide substrate, including: a plurality of curved waveguides; a rectangular coordinate system is established with the bending direction of the curved waveguides as the y-axis and the light propagation direction as the x-axis; and based on the rectangular coordinate system , the curved waveguide is periodically bent in the curved direction along the propagation direction; a plurality of curved waveguides are arranged in parallel along the y-axis direction, and the curved waveguides are perpendicular to the y-axis direction, forming A curved waveguide array; realizing the optical waveguide signal transmission function or the optical waveguide directional coupling function of the optical waveguide by adjusting the coupling coefficient between the curved waveguides. The optical waveguide provided by the invention gets rid of the sensitivity and dependence on parameters such as waveguide spacing and wavelength under high-density integration, so it has structural robustness and broadband characteristics.

Description

technical field [0001] The invention relates to the field of integrated photons, in particular to a high-density integrated optical waveguide. Background technique [0002] With the rise of the modern Internet of Things, big data and other industries, human society's demand for information processing such as higher speed, larger broadband network capacity, and stronger confidentiality has increased sharply, and electrical chips have obviously reached the bottleneck stage. In the same way as the development of integrated circuits, integrating two or more discrete optical components on a small substrate (below the centimeter level) can form an integrated optical chip system that realizes a certain function. It has high speed, low power consumption and Due to the advantages of high-density integration, it is expected to become a promising development direction for high-capacity, high-speed information systems. [0003] Silicon-on-insulator (SOI) has become one of the most wide...
