Claim Text:
1. A method of forming a single-mode polymer waveguide array assembly, the method comprising the steps of: applying an undercladding material to cover a plurality of projecting portions prepared on an inner surface of an initial process mold, said projecting portions each corresponding to one of a plurality of cores in a waveguide array; applying ultraviolet (UV)-transparent cover film to the top surface of the undercladding material; exposing the undercladding material to UV light via the applied cover film to UV-cure the undercladding material and bond the cover film to the undercladding material; removing the applied cover film and cured undercladding material together from the initial process mold; bridging an intermediate process mold and a plurality of ferrules provided at both ends of the intermediate process mold with the removed applied cover film and cured undercladding material, these being inserted toward a plurality of inner faces of the plurality of ferrules with the applied cover film side facing down; filling a plurality of trench or recessed portions of the cured undercladding material with a core material; exposing the core material to UV-light to cure the core material; applying an overcladding material to the cured core material and cured undercladding material; and curing the applied overcladding material.
