ABSTRACT:
The present invention provides a laser diode realizing improved light detection precision. The laser diode includes a stack structure in which a first semiconductor layer of a first conduction type, an active layer, and a second semiconductor layer of a second conduction type are included in this order; a photodetection layer; and a plurality of light absorption layers provided on the corresponding position of antinodes or nodes of standing waves of light output from the active layer.
