Abstract
PURPOSE: To obtain a laser with monitor where troublesome positioning is needless at an assembling time and positional slippage is not generated by the vibration in a using time.
CONSTITUTION: N-type GaAlAs 11b, n-type GaAs 11c, and n-type GaAlAs 11d are laminated on face (100) of n-type GaAs substrate 11a, and p-type layers 12 and 13 which have a depth to reach layer 11b are formed at a interval of approximately 10μm by Zn diffusion from main face 11e. Next, after annealing, AuCr alloy electrodes 14 and 15 and AuNi electrode 16 are provided on main face 1 and reverse face 11f respectively. When a voltage is applied as prescribed, laser beam is emitted in active layer 12, and potential difference is generated in layer 13 correspondingly to the light output of layre 12. Then, since the potential difference corresponding to the light output of layer 12 is generated in monitoring resistance 18, the power source is controlled according to this change to obtain a stable laser output. In this constitution, light emission part 12 and light receiving part 13 are provided in the same substrate, so that positional slippage can be prevented.
