Abstract
An optical device can include an end-fire optical phased array including an optical splitter to split an optical signal into a plurality of channels, an optical phase controller to control a phase of the optical signal transmitted from the optical splitter, and an end-fire optical radiator to radiate the optical signal transmitted from the optical phase controller. A lens can be further positioned on a path of the radiated optical signal to control a vertical divergence angle of the radiated optical signal.
