Abstract
A vertical-cavity surface-emitting laser array includes a substrate having an element forming area, multiple columnar structures formed in the element forming area on the substrate, and at least one metal wire formed adjacent to the multiple columnar structures. Each columnar structure includes a lower semiconductor reflector of a first conductivity type, an upper semiconductor reflector of a second conductivity type, and an active region formed between the lower semiconductor reflector and the upper semiconductor reflector. The columnar structure emits light in a direction perpendicular to the substrate. The at least one metal wire has a distortion applying segment that extends in the same direction relative to the multiple columnar structures.
