Outline of Final Research Achievements

Novel functional nonvolatile spintronics devices are important for ultra-low power consumption information and communication society. We have demonstrated, for the first time, circularly polarized lasing of optical communication wavelength vertical cavity surface emitting lasers (VCSELs) by optical spin injection. Furthermore, we have conceived a novel high-speed direct modulation scheme in spin-controlled VCSELs and demonstrated the concept by achieving a 3-dB bandwidth of 23GHz.
