Abstract: Provided is a laser radar system. The laser radar system includes a first transmission and reception unit sequentially radiating a first laser beam to a plurality of locations within a first view range and receiving a reflected light; and a second transmission and reception unit sequentially radiating a second laser beam to a plurality of locations within a second view range and receiving a reflected light, wherein each of the first transmission and reception unit and the second transmission and reception unit is fixed to a loader and independently searches for the first view range and the second view range.

Abstract: An optical waveguide structure includes a substrate and a core structure disposed on the substrate. The substrate includes a first waveguide region, a second waveguide region, and a transition region between the first waveguide region and the second waveguide region. The core structure includes first core segments arranged in a first direction and a second direction crossing the first direction on the transition region. The core structure includes second core segments arranged in the first direction and the second direction on the second waveguide region. The first direction and the second direction are parallel to a top surface of the substrate.
