Novel ultrasmall Si-nanowire-based arrayed-waveguide grating interleaver with spirals
2008 (English)In: Optics Communications, ISSN 0030-4018, E-ISSN 1873-0310, Vol. 281, no 13, 3471-3475 p.Article in journal (Refereed) Published
Abstract [en]

A novel layout is presented to achieve an ultrasmall arrayed-waveguide grating (AWG) interleaver based on Si-nanowire waveguides. Spiral waveguides are inserted in the middle of arrayed-waveguide 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 mu m x 372 mu m (0.027 mm(2)).
