We fabricated a silicon (Si) laser by applying a dressed-photon–phonon assisted annealing process to a ridge-type light waveguide that we fabricated via siliconon- insulator (SOI) technology. We also evaluated a nearinfrared Si photodiode having optical gain to estimate the differential gain coefficient for designing lightwaveguides. We designed light waveguides having a thickness of 15 μm to realize...
In Japan, the treatment of waste concrete scraps has been one of the environmental issues. Therefore, new application using pulsed power discharge has been developed as the recycling method of the coarse aggregates from the waste concrete scraps. In the work, the dependences of the quality of the recycled coarse aggregate by the repetitive pulsed discharge treatments on the consumption energy were...
