Abstract:
A method of producing a semiconductor light emitting device comprising on a substrate a first semiconductor light emitting element and a second semiconductor light emitting element for emitting light of different wavelengths from each other, including the steps of:forming on the substrate by an epitaxial growth method a first stack comprised of at least a first clad layer of a first conductivity type, a first active layer, and a second clad layer of a second conductivity type; removing the parts of said first stack other than the part at the first semiconductor light emitting element formation region; forming on the substrate by an epitaxial growing method a second stack comprised of at least a third clad layer of the first conductivity type, a second active layer, and a fourth clad layer of the second conductivity type; and removing the parts of said second stack other than the part at the second semiconductor light emitting element formation region; at least said first active layer and said second active layer being formed by different compositions from each other.
