英文摘要	PURPOSE:To allow the effect of the current inhibiting layer to be held even if the optical output is increased by forming in the current inhibiting layer a current inhibiting region which is of the same conductivity type and has a forbidden band width broader than the surrounding region. CONSTITUTION:When a semiconductor laser reaches the oscillation state, part of the light is absorbed by a first current inhibiting region 5 made of n-GaAs and is converted to an electron-positive hole pair. Electrons do not flow out into a second clad layer 4 or a third clad layer 8, but they are stored in a current inhibiting layer comprised of the first current inhibiting region 5, a second current inhibiting region 6 and a third current inhibiting region 7. If electrons are stored in the current inhibiting layer, the band in the current inhibiting layer will lift. However, even in the maximum lift state, the barrier effect of the valence band of the second current inhibiting region 6 on the minority carrier is not lost, whereby the current inhibiting effect is maintained.
