Abstract: PURPOSE: A temperature-independent arrayed waveguide grating is provided to compensate the shift of wavelengths according to a variation of temperature by forming the first slap with media having different refractive indexes. CONSTITUTION: A temperature-independent arrayed waveguide grating includes an input waveguide, a grating, a first slap, a second slap, and an output waveguide. The input waveguide(130) is used for receiving an optical signal from the outside. The grating is used for dividing the optical signal into beams having different wavelengths. The first slap(140) is used for connecting the input waveguide to the grating. The first slap is formed with two layers having different refractive indexes. An image of the output beams of the grating is formed on the second slap. The output waveguide is used for outputting the output beams of the output part of the second slap.
