| Summary: | We report on low-loss, low-crosstalk, and compact arrayed waveguide gratings (AWGs) based on a 200-nm-thick-Si<sub>3 </sub>N<sub>4</sub>-core platform. High-resolution fabrication processes realized four types of Si<sub>3</sub>N<sub>4 </sub> AWG devices: 8 channel × 200 GHz, 16 channel × 100 GHz, 16 channel × 50 GHz, and 16 channel × 25 GHz AWGs. The insertion loss values of the four devices were 1.5 dB, 1.7 dB, 1.8 dB, and 2.7 dB; the corresponding crosstalk values were –24 dB, –21 dB, –20 dB, and –13 dB; footprints were 1.8 × 0.6 mm<sup>2</sup>, 2.2 × 0.7 mm<sup>2</sup>, 3.7 × 0.7 mm<sup>2</sup>, and 6.8 × 0.7 mm<sup>2</sup>, respectively. |
