Abstract
An optical beam steering device and a method for beam steering are described. The optical beam steering device including: a laser source coupled to an optical phased array (OPA) The OPA includes: a beam splitter network optically coupled to the laser source and configured to split a laser beam generated by the laser source into N outputs to generate an output optical beam; a first network of first phase shifters configured to steer the output optical beam in a first direction away from a longitude direction; and a second network of second phase shifters configured to steer the output optical beam in a second direction away from the longitude direction, the second direction being opposite to the first direction.
