Abstract

In this paper, we report the insertion loss and adjacent crosstalk for tapered and conventional configuration of double S-shaped design of arrayed waveguide grating (AWG) using 1.2 μm and 1.0 μm core width. The 13-channel AWG on silicon-on-insulator (SOI) was simulated using beam propagation method (BPM) at central wavelength of 1.49 μm, producing a transmission spectrum ranging from 1310-1620 nm. Tapered AWG for both core widths gave the lowest insertion loss of < 7 dB while only the AWG with the 1.2 μm core width produced the lowest crosstalk at <-19 dB compared to the other configurations. A 13-channel transmission spectrum of the AWG device has been produced which fits closely the standard ITU-T CWDM wavelength grid.
