Abstract: A super-compact arrayed waveguide grating (AWG) wavelength division multiplexer based on a sub-wavelength grating is provided and includes an input waveguide, a first planar waveguide, an arrayed waveguide, a second planar waveguide, and the output waveguide that are sequentially connected. The input waveguide has 1 port, and the output waveguide has 8 ports. The arrayed waveguide includes 50 equivalent uniform strip waveguides with the same length difference, and each of the equivalent uniform strip waveguides is configured as a sub-wavelength grating structure, thereby forming the effect of increasing group refractive index or transmission delay based on a slow light effect. The 8 channels with a channel spacing of 200 GHz have the minimum adjacent channel crosstalk of less than ?27 dB, and the overall size is within 300×230 ?m2. In the multiplexer, the overall integration size of the device is reduced by an order of magnitude.
