Abstract:
A device, comprising:a fiber module having a first substrate with a first surface fabricated to form an elongated groove with two through holes penetrating said first substrate and formed on both ends of said groove, and a fiber engaged to said first substrate by passing through both said through holes to have a portion laid in said elongated groove, wherein cladding of said portion is removed to form a fiber coupling port for evanescently coupling energy into and out of said fiber; and a waveguide module having a second substrate configured to have an optical waveguide with a waveguide portion to form a waveguide coupling port for evanescently coupling energy into and out of said waveguide, wherein said waveguide module is engaged to said fiber module to place said elongated groove substantially parallel to said waveguide and to interface said fiber coupling port with said waveguide coupling port for evanescent optical coupling between said waveguide and said fiber.
