ABSTRACT:
A laser diode capable of having the position and emitting direction of its laser beam readily varied as desired through control over injected currents. The laser diode has an independent current injecting region in a waveguide (intermediate region) near the mirror facet of the laser diode, the center axis of the current injecting region differing from that of another waveguide (straight region). Suitably modulating the currents injected into the current injecting region generates a desired refractive index profile, whereby beam scan is obtained as desired.
