Abstract

Stepped and scaleable 64-increment optical buffering and time-delay provision via two concatenated 8times8 arrayed-waveguide gratings is described, requiring only 1.6% of typical total waveguide-length. A method to reduce computational effort and to minimize waveguide crossovers during device design is also discussed. Finally, we demonstrate perfect dispersion for WDM:TDM conversion for 16 wavelengths/time-slots.
