Abstract (in Japanese) (See Japanese page) 
(in English) Significant expansion and effective use of optical frequency resources are expected to be an important technology for future optical communication. Recently, we focused on a development of the novel optical frequency resource in a Thousand-band (T-band; 1000-1260nm), and O-band (1260-1360nm). Optical gain devices with InAs/InGaAs quantum dot (QD) structure are considered to be useful photonic gain material in those wavebands. In this paper, we investigated broadband QD optical-gain material using the sandwiched sub-nano separator (SSNS) which provides a high quality QD and a modulated structures. We also constructed wavelength-tunable QD light source using the broadband QD optical-gain material. As a result, a broadband wavelength-tunability was successfully demonstrated in the 1.2-1.3 μm wavebands.
