Laser array and lidar

Abstract

Embodiments of this application provide a laser array and a lidar, and relate to the field of optical sensing technologies. A differential resistance of the laser array is adjustable, and optical power of emitted laser light that is output is adjustable. The laser array includes a first laser and a second laser. The first laser includes a first reflection layer, a first active layer, and a second reflection layer that are sequentially disposed in an epitaxial direction. A first oxide aperture is provided in the second reflection layer. The second laser includes a third reflection layer, a second active layer, and a fourth reflection layer that are sequentially disposed in the epitaxial direction. A second oxide aperture is provided in the fourth reflection layer. A light blocking layer is further disposed on a side, away from the second active layer, of the fourth reflection layer. A projection of the light blocking layer on the second active layer overlaps a projection of the second oxide aperture on the second active layer. The first laser is electrically connected to the second laser.
