Abstract
PURPOSE: To improve the linearity of the characteristic of a current to a photo output, by constituting stripes so that the variation in gain distribution will be generated at a prescribed position inside a luminous region.
CONSTITUTION: On n-type GsAsl, n-type Ga1-xAlxAs2, p-type Ga1-yAlyAs3, p-type Ga1-xAlxAs4, and p-type GaAs5 are stacked, and S is selectively diffused into the stripe region of width W to form n-type conversion regions 6 to 8, thereby obtaining current stopping regions. In this way, more than two injection current paths for causing luminescence are formed so that the variation in gain distribution will be at a fixed position, and the oscillation with the transverse mode made stable is caused in order to make it possible to maintain linearly the relation of a current to a photo output over the broad current range. Consequently, the deterioration of a photo output waveform and the decrease of the coupling efficiency with optical fiber can be eliminated
