Abstract
Both an electric energy applying mechanism and an optical waveguide mechanism can be provided to an ITO layer (transparent electrode) by constituting an optical waveguide so as that the guided mode profile spread into the ITO layer. Also a bonding pad is provided to supply a power and apply an electric field onto the ITO layer. Accordingly, a device structure can be simplified and thus improvement in yield of the optoelectronic device having an optical waveguide and improvement in parameters of the optoelectronic device can be achieved.
