Abstract
A one-dimensional planar beam forming and steering optical phased array chip is a simple building block of a two-dimensional beam forming and steering solid-state lidar, enabling manufacturing of said lidars at high yield and low cost through the use of a plurality of said chips. Innovative photonic integrated circuit chip architectures that follow design for manufacturing rules enable said building blocks.
