Abstract

The semiconductor laser device of the present invention includes a GaAs substrate and a multi-layer structure formed on the GaAs substrate. The multi-layer structure includes an active layer for emitting light. The active layer includes an InN.sub.x As.sub.y P.sub.1-x-y (where 0<x<1 and 0.ltoreq.y<1) layer that is lattice-matched with the GaAs substrate.
