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.

Acoustically driven arrayed waveguide grating
Optics Express, 2015 We demonstrate compact tunable phased-array wavelength-division multiplexers driven by surface acoustic waves (SAWs) in the low GHz range. The devices comprise two couplers, which respectively split and combine the optical signal, linked by an array of single-mode waveguides (WGs).
