Abstract: Provided are a vertical-cavity surface-emitting laser, a manufacturing method, a distance measuring device, and an electronic device. The vertical-cavity surface-emitting laser includes a lower electrode, a substrate, a lower Bragg reflector, an active area, a current limiting layer, an upper Bragg reflector, a protective layer, and an upper electrode. The upper electrode includes at least two sub-electrodes, the at least two sub-electrodes are electrically connected, and the at least two sub-electrodes define one or more light-exiting windows. Each sub-electrode is provided with a corresponding light-exiting window so that the luminous power is increased. Each sub-electrode defines the light-exiting window, and a plurality of sub-electrodes are electrically connected so that the distribution uniformity of the light spots is increased, and the quality of the laser beam is improved.
