摘要：

Using vertical-cavity surface-emitting lasers with two p-type electrodes, continuous output beam steering was achieved for the (first time by controlling the injection current profile. The far-field peak position can be shifted linearly by varying the ratio between injection currents into the two p-type electrodes. The deflection angle measured from the surface normal direction ranges from -1.3 degrees to +1.0 degrees. Also, we investigated operating characteristics that are important for optical processing such as optical fuzzy inference.
