摘要：
A novel layout is presented to minimize the size of an arrayed-waveguide grating (AWG) demultiplexer based on Si nanowire waveguides, in particular when a high diffraction order is required. A series of microbends are inserted in the middle of arrayed waveguides to increase the lightpath difference while keeping small separation between arrayed waveguides. A designed ultrasmall AWG with a narrow channel spacing of 0.8nm has a total size of only about 0.505mm x 0.333mm (0.165mm(2)). (c) 2006 Optical Society of America.
