Abstract

A 32×32 100 GHz silicon photonic integrated arrayed waveguide grating router (AWGR) is experimentally demonstrated for dense wavelength division multiplexing (DWDM) applications. The dimension of the AWGR is 2.57 mm×1.09 mm with a core size of 1.31 mm×0.64 mm. It exhibits 6.07 dB maximum channel loss non-uniformity with −1.66 dB best-case insertion loss and average channel crosstalk of −15.74 dB. In addition, in the case of 25 Gb/s signals, the device successfully realizes high-speed data routing. The AWG router provides clear optical eye diagrams and low power penalty at bit-error-rates of 10−9.
