Abstract
A laser beam steering device and a system including the same are provided. The laser beam steering device includes a waveguide through which a laser beam passes, and a cladding layer disposed on the waveguide. The cladding layer has a refractive index which changes according to an electrical signal applied thereto and thus a phase of a laser beam passing through the waveguide may be changed.
