Lidar sensing, beam steering & combining
We present a 2-dimensional optical phased array (OPA) realized with a 3-dimensional PolyBoard chip. Beam steering was demonstrated with an initial 2x4 array. Without any front lens, the maximum steering angle is about 10°. This technology can scale up to 32x256 arrays. The OPA module is coupled to a standard single-mode fiber and a ribbon cable for beam control.
