PURPOSE: A photonic device is provided to enhance electron-hole recombination and to efficiently emit photons by using a phonon generator. CONSTITUTION: Silicon possesses an indirect band-gap, which limits its use in some photonic applications. A phonon generator is included in a silicon-based device, which promotes electron-hole recombination and so allows silicon to emit photons efficiently. Photons may be generated by optical or electrical stimulation or as a result energy relaxation of hot-electrons.
