Abstract :
A novel layout is presented to achieve an ultrasmall arrayed-waveguide grating interleaver based on Si nanowire waveguides. Spiral waveguides are inserted in the middle of arrayed waveguides to obtain a large lightpath (required for the ultra-high diffraction order) in a small occupied area. A designed ultrasmall AWG interleaver with a free spectral range of 0.8 nm has a total size of only about 73 mum x 372 mum (0.027 mm2).
