"Si nanophotonics" controls light by employing a nano-scale structural technology. Featuring state-of-the-art technologies to manufacture LSI chips, Si nanophotonics technology enables impressive miniaturization and achieves low power consumption compared to the conventional optical elements technologies. Optical signal transmission of the LSI chip has not hitherto been realized, however by adopting this Si nanophotonics technology to the elements of an LSI, NEC demonstrated the possibility to significantly improve LSI performance. With this technology NEC is proposing to create new devices to support next generabon networks and LSI innovations.
