摘要：

A novel design for an ultrasmall arrayed-waveguide grating (AWG) demultiplexer based on a Si nanowire waveguide is presented. The two free propagation regions (FPRs) are overlapped so that the structure becomes more compact than the layout of a conventional design. Each half of an arrayed waveguide includes three straight sections and two bending sections, and all these sections are connected smoothly in sequence. Some recursive formulas for determining the geometrical parameters of the novel layout are derived. Numerical simulation results are given.
