Abstract:
An optical chip according to the present invention is formed into a projecting shape expanded toward either side at the center. A waveguide substrate has a layout in which arrayed waveguide grating type optical multiplexer/demultiplexer circuits, each having a curve direction of an array waveguide reverse to each other, are arranged in combination, and the optical chips are cut out of the waveguide substrate. A method for fabricating the optical chip according to the present invention can enhance an optical chip yield rate, and further, can fabricate an optical chip having the shape for stabilizing optical characteristics of the arrayed waveguide grating type optical multiplexer/demultiplexer circuit.
