Abstract

The NxN arrayed-waveguide grating (AWG) multi/demultiplexer [1] has become one of the key integrated-optic components in wavelength-division multiplexing (WDM) communication networks. The reported methods [2]-[4] for the design and performance simulation of AWGs have so far been limited to 2-D scalar-wave analysis using the effective-index method in the vertical direction. In this paper we present a computationally efficient 3-D vector-wave technique for analyzing and designing AWGs including the effects of waveguide-slab junction coupling losses and TE and TM polarizations.
