摘要：PURPOSE: A multi channel optical communication uniform apparatus in module loss change using a mode mismatch is provided, which makes a uniform output power of each channel being output from a completed module. CONSTITUTION: According to an optical device comprising an input waveguide(30) and an output waveguide(38) and an arrayed waveguide grating(AWG) connecting the input and the output waveguide, an output light uniform unit causing a mode mismatch of a propagating output light because width of the output waveguide is different each other. And an optical fiber block(40) comprises a number of optical fibers having a constant distance between them, and its center coincides with a center of the output waveguide. And the above optical fiber is combined to an output port of each corresponding output waveguide respectively.
