To develop a new optical frequency resource for the optical communications, we focused on T-Band (1000-1260nm) and the O-Band (1260-1360nm). We are promoting the research and development of optical gain devices operating in this band.We have developed a wideband gain chip using InAs quantum dots in the 1.0 μm band and ASE free wavelength tunable light source using it.
