Latest Patents

Xiaojun Xie holds a patent for a super-compact arrayed waveguide grating (AWG) wavelength division multiplexer based on a sub-wavelength grating. This multiplexer includes an input waveguide, a first planar waveguide, an arrayed waveguide, a second planar waveguide, and an output waveguide that are sequentially connected. The input waveguide has one port, while the output waveguide features eight ports. The arrayed waveguide consists of 50 equivalent uniform strip waveguides, each configured as a sub-wavelength grating structure. This design significantly reduces the overall integration size of the device by an order of magnitude, achieving a compact size of 300×230 μm. The multiplexer operates with eight channels, each having a channel spacing of 200 GHz, and demonstrates a minimum adjacent channel crosstalk of less than −27 dB.
