ABSTRACT:
A semiconductor device comprises a base semiconductor portion and, thereon, first and second elevated semiconductor portions separated by a channel. The uppermost surface of the first elevated semiconductor portion carries a metal electrical contact layer and the uppermost of the second a dielectric layer. The surfaces defining the channel are substantially free of metal and dielectric.
The structure can be used in a ridge waveguide laser, the first elevated semiconductor portion constituting the ridge (7", 8").
Distributed feedback corrugations may be incorporated in such devices (6), or in other ridge waveguide structures.
