Mesh-electrode type and flip-chip type silicon light-emitting diodes were fabricated by using dressed photons. Their emission spectral profiles showed several peaks originating from phonons in a dressed-photon–phonon, from which the existence of a photon breeding phenomenon was confirmed. The highest optical output power emitted from these devices was 2 W at a substrate temperature of 77 K. The highest optical power density from the flip-chip type was as high as eight-times that from the mesh-electrode type.
