ABSTRACT:
A semiconductor opto-electronic device including at least one electronic function component (62), at least one optical function component (60) and a mode transformer associated with the optical function component. At least some layers of semiconductor material constituting the electronic function component also form optical layers in the mode transformer zone and, at least in the mode transformer zone, these semiconductor material layers are non-absorbent at the operating wavelength. The mode transformer is preferably etched in the shape of an hourglass.
