Light emitting semiconductor device
摘要:
In a carrier injection type light emitting semicon­ductor device with a QW structure, a p-type impurity doped layer (42) and/or an n-type impurity doped layer (45) are inserted into an optical wave guide layer (4) so as to cancel an internal electric field in an active region (43).
