摘要：

We demonstrate 32-channel dispersive optical phased arrays on a Si3N4-on-SOI integration platform. The phase difference is introduced by the arrayed waveguide. Beam steering in phased-array direction with an aliasing-free range of 22.4 degrees and free spectrum ranges of similar to 60 nm and similar to 6 nm is achieved. Meanwhile, the main lobe is deflected simultaneously by 19.67 degrees in the other direction by tuning the wavelength from 1500 nm to 1630 nm. Measurement results show that the dispersive optical phased array provides a compact, low-power and massively parallel solution for LiDAR applications.
