Description

field of invention [0001] The present invention mainly relates to 1×N thermo-optic and electro-optic waveguide optical switch arrays, and relates to the technical field of manufacturing polymer waveguide optical switch arrays. Background technique [0002] Integrated waveguide structured optical switches are widely used in optical switching systems of optical communications, optical path monitoring and maintenance systems, data networks, optical fiber sensor systems, and optical fiber measurement systems. The working mechanism of the integrated waveguide structured optical switch is generally to use the thermo-optic effect or the electro-optic effect to change the refractive index of the optical waveguide medium to realize the function of controlling the on-off of the optical path or changing the direction of light propagation. According to different modulation mechanisms, current drive or voltage drive mode is adopted. Organic polymer integrated optical switch is a new typ...
