Abstract
An electroluminescent material slot waveguide generates light in response to current injection. In one embodiment, the waveguide is formed as part of an optical resonator, such as ring resonator waveguide or distributed Bragg reflector with an anode and cathode for electrical stimulation. A compact, electrically-driven resonant cavity light emitting devices (RCLED) for Si microphotonics may be formed. Several different rare-earth ions, such as erbium, terbium and ytterbium, can be used to dope SiO2 in order to emit light at different wavelengths.
