Abstract
A light beam can be steered using a non-mechanical beam steerer structure. For example, a combination of sub-aperture and full-aperture beam steering structures can be used (e.g., corresponding to regions of controlled variation in an index of refraction). The sub-aperture elements can include tapered structures defining a saw-tooth or triangular footprint in the plane in which the in-plane steering is performed. Respective rows of sub-aperture tapered structures can be configured to controllably steer the light beam in the first in-plane direction, wherein at least one row of sub-aperture tapered structures defines a first base region edge that is tipped at a first specified in-plane angle relative to a second base region edge defined by another row. Use of the tipped configuration can simplify a configuration of the beam steerer structure, such as allowing a configuration lacking a compensation plate at the input.
