ABSTRACT:
The present invention has an object of enhancing the tolerance of setup positioning error of an optical multiplexer/demultiplexer which uses a multi-mode optical waveguide. For this sake, the invention is designed to couple the multi-mode optical waveguide with a single-mode optical waveguide directly. In another configuration of this invention, there is provided between both optical waveguides a single-mode optical waveguide having its length set to be approximately equal to zero, or equal or approximately equal to the period of interference between the 0th-order mode and a radiative higher-order mode of the single-mode optical waveguide.
