The NTT Nanophotonics Center (NPC) was established in April 2012, and is now composed of several groups involved in nanophotonics research and based in NTT’s Basic Research Laboratories and Device Integration Laboratories. Our aim is to develop a full-fledged large-scale photonic integration technology by which we will be able to densely integrate a large number of nano-scale photonic devices with various functions in a single chip. Furthermore, we are targeting a huge reduction in energy consumption for photonic information processing by taking advantage of nanophotonics technology.
