Abstract

We demonstrate a low-crosstalk arrayed waveguide grating (AWG) utilizing silicon nitride material platform. Compared to the traditional uniform waveguide structure, the un-uniform array waveguide structure achieves a -6.2 dB improvement of the crosstalk. A crosstalk of –25.3 dB and the insertion loss of –4.3dB was realized with a center wavelength of 910 nm. We also measured the temperature stability and fitted a wavelength shift of 6.57 pm/°C.
