Method for formatting the facet of optical waveguide element

摘要

Disclosed is a method for formatting facets of an optical waveguide element. The method according to the present invention includes the steps of: (1) attaching auxiliary blocks so they are protruded from the upper portions of both ends of the optical waveguide element by a means of an adhesive coupling, and coating with the adhesive from the bottom of the protruded auxiliary blocks to the end facets of the core and the cladding layer of the optical waveguide element; (2) contacting the auxiliary blocks with a thermal plate, which has undergone an optical facial treatment, so that the facets of the optical waveguide element, including the auxiliary blocks formed in the first step can be shaped into a predetermined oblique angle; (3) applying pressure on the optical waveguide element including the auxiliary blocks in a downward direction against the thermal plate until the adhesive coated on the facets of the optical waveguide element is completely melted; (4) moving the optical waveguide element including the auxiliary blocks in a horizontal direction along the thermal plate at the moment when the adhesive coated on the facets of the optical waveguide element including the auxiliary blocks is completely melted; and, (5) removing the optical waveguide element including the auxiliary blocks from the thermal plate at the moment when the adhesive coated on the facets of the optical waveguide element including the auxiliary blocks is completely removed.
