New Analytical Arrayed Waveguide Grating Model
Journal of Lightwave Technology, 2013 An analytical model of star couplers in arrayed waveguide gratings (AWG) is derived. By retaining the real 1D mode shapes, the model is able to calculate the star coupler response to fundamental modes, as well as higher-order modes. This is desirable for modeling passband flattened AWGs. The model can calculate the response of an AWG very fast, because

Low crosstalk Arrayed Waveguide Grating with Cascaded Waveguide Grating Filter [PDF]
Journal of Physics: Conference Series, 2011 We propose a highly compact and low crosstalk arrayed waveguide grating (AWG) with cascaded waveguide grating (CWGF). The side lobes of the silicon nanowire AWG, which are normally introduced by fabrication errors, can be effectively suppressed by the CWGF. And the crosstalk can be improved about 15dB.
