Abstract
A graded-index polymer waveguide () and a manufacturing method thereof are provided. The method includes providing a waveguide substrate (); manufacturing a waveguide lower cladding layer () on a surface of the waveguide substrate (); coating a material of a waveguide core layer () having UV photosensitivity on a surface of the waveguide lower cladding layer () away from the waveguide substrate (); performing a hot imprinting process for the material of the waveguide core layer by means of a flexible transfer film mold and forming a waveguide core layer () having an imprinted waveguide link structure; performing a heat treatment process for the waveguide core layer (); performing a pre-exposure process for the waveguide core layer; coating a waveguide upper cladding layer on a surface of a waveguide core layer (); and curing the waveguide core layer () and the waveguide upper cladding layer ().
