Abstract
A packaging device for alignment between a planar lightguide circuit and an optical-fiber block is disclosed. The device includes a planar lightguide circuit and a single optical-fiber block. The planar lightguide circuit includes an input port of an input waveguide, a plurality of output ports of output waveguides, arranged on the same surface as the input port of the input waveguide, and at least one dummy waveguide arranged abutting the outermost end of the output waveguides. An output port of the dummy waveguide is arranged on the same surface. The single optical-fiber block includes a plurality of ports corresponding to the input/output ports. The input/output ports are coupled in alignment with the input port of the input waveguide and the output ports of the output waveguides. The invention enables making a single processed alignment of the input/output ports of the planar lightguide circuit and the single input/output ports.
