Paper Abstract

In this paper, an accurate Fourier Optics method of designing AWG demultiplexer based on high-index-contract Silicon-on-Insulator (SOI) materials is presented. The typical SOI photonic wire waveguide has a cross section of 400×340nm2 satisfying single-mode condition, and operating central wavelength is 1.5500μm. A three-stigmatic-points method is also applied in order to improve the accuracy, considering the aberration theory. Furthermore, our AWG has another important characteristic--the flat field of the output ports. In the example presented here, we design a 1×256 channel AWG with 0.1-nm channel spacing. The simulation result shows that the insert loss is almost 0dB for the central and peripheral output ports as well, representing a good uniformity. Meanwhile, the crosstalk to the adjacent channel is 14.4dB. Free spectral region (FSR) equals to 30nm as designed.
