摘要：

We present a hybrid integrated photonic circuit with tunable arrayed waveguide gratings (AWGs) as (DE-)MUX stages for optical modulators for use in parallel convolution processing. The simulated and fabricated AWGs have 16 outputs with 500 GHz channel spacing centered around 193.1 THz. A peak insertion loss of 4.5 dB is achieved with a 3 dB channel bandwidth of 380 GHz. Heater electrodes over the array waveguides enable tuning of more than 4 nm. The AWGs are hybridly integrated with indium phosphide-based modulators and amplifiers. This paves the way for integrated light modulation sources for the use in vector-matrix multiplication.
