Provided is a light emitting component capable of switching a laser diode to emit light at high speed as compared with a case where there is no ON state regarded as a logical value “0”. A light-emitting component C includes a plurality of laser diodes LD1, LD2, LD3,..., Which are set to an on state and an off state regarded as a logical value “1”, a logical value “0”, and a laser. A plurality of control thyristors S1, S2, S3,... That are stacked with each of the diodes LD1, LD2, LD3,... And set to an on state by turning the laser diodes LD1, LD2, LD3,. And the control thyristors S1, S2, S3,... Are set to the on state, and the logic value “0” is set before the timing at which the laser diodes LD1, LD2, LD3,. And a light emission setting unit 102 for setting the ON state. [Selection] Figure 1 |
