Abstract:
A method of pigtailing an optical waveguide device, comprising the steps of:preparing an optical waveguide device comprising:a substrate having a lateral surface and a top surface;an optical waveguide formed on said top surface, whose shape comprises:an input port terminating at said lateral surface;a crosswise portion extending from said input port perpendicular to said lateral surface;a first arc portion extending from said crosswise portion;a first lengthwise portion extending from said arc portion and running parallel to said lateral surface;a branch splitting said first lengthwise portion;a plurality of second lengthwise portions extending from the branch and running parallel to said lateral surface;a second arc portion extending from one of the second lengthwise portions; anda second crosswise portion extending from said second arc portion perpendicular to said lateral surface, and terminating at an output port on said lateral surface;preparing an optical fiber array module whose optical fibers terminate on one surface of the optical fiber array module and are arranged to align with said input and output ports of said optical waveguide device when said lateral surface of the optical waveguide device is aligned with said one surface of said optical fiber array module;aligning said lateral surface of said optical waveguide device with said one surface of said optical fiber array module; andattaching said lateral surface of said optical waveguide device with said one surface of said optical fiber array module.
