Abstract :
Arrayed waveguide gratings (AWG), high performance optical (de)multiplexers, are central components in the realization of high-speed dense wavelength division multiplexing (DWDM) networks. However, their large size and structural complexity inhibit a thorough mathematical analysis, which restricts design. In this paper we adapt the finite difference-beam propagation modeling method (FD-BPM) to examine hitherto largely ignored effects in the function-critical arrayed waveguides (AW). Coupling effects are examined, along with higher-order grating modes, and their potential to increase the inter-channel crosstalk of the system, extending existing analysis.
