Abstract

PURPOSE:To obtain converging directional emitting light from the semicondoctor light emitting device by increasing the diameter of a clad layer larger than an active layer, forming a reverse conductivity semiconductor layer as a base and sufficiently enclosing a current. CONSTITUTION:This device has a base of three layers having an N type GaAs substrate 21, an N type Ga1-xAlxAs layer 22 and a P type Ga1-xAlxAs layer 23, an N type Ga1-xAlxAs (0<=x<=1) clad layer 25 inserted into the hole of the base, a P type Ga1-yAlyAs (y<x, 0<=y<=0.4) active layer 26 formed above the surface of the base with hetero junction with the layer 25, and a P type Ga1-xAlxAs clad layer 27 formed on the layer 26 as hetero junction structure, and the diameter of the projection at the base side of the layer 25 is larger than that of the active layer.
