He joined NTT Basic Research Laboratories in 1991. He was a guest scientist in Delft University of Technology, Delft, the Netherlands during 1997-1998. Since 2003, he is also a guest associate professor at Tokyo Institute of Technology. Since 1991 he has engaged in the study of semiconductor fine structures fabricated by focused-ion-beam technique and electron-beam lithography technique, transport characteristics of semiconductor quantum dot. His current interests are single-electron dynamics in quantum dots, and their application to quantum information technologies. He is a member of the Japan Society of Applied Physics, and the Physical Society of Japan.

Masaya Notomi was born in Kumamoto, Japan, on 16 February 1964. He received his B.E., M.E. and Dr. Eng. degrees in applied physics from University of Tokyo, Tokyo, Japan in 1986, 1988, and 1997, respectively. In 1988, he joined Nippon Telegraph and Telephone Corporation, NTT Optoelectronics Laboratories, Atsugi, Japan. Since then, his research interest has been to control the optical properties of materials and devices by using artificial nanostructures, and engaged in research on semiconductor quantum wires/dots and photonic crystal structures. He has been in NTT Basic Research Laboratories since 1999, and is currently working on light-propagation control by use of various types of photonic crystals. From 1996-1997, he was with Linkoping University in Sweden as a visiting researcher. He is also a guest associate professor of Tokyo Institute of Technology (2003- ). He is a member of the Japan Society of Applied Physics, and the American Physical Society.

Toshiki Makimoto was born in Tokyo on January 16, 1960. He received the B.E., M.S. and Ph.D. degrees in electrical engineering from the University of Tokyo in 1983, 1985 and 1993, respectively. He joined NTT Basic Research Laboratories in 1985. He was a visiting researcher in University of California, Santa Barbara, USA during 1993-1994. Since 1985, he has engaged in epitaxial growth of III-V compound semiconductors using metalorganic vapor phase epitaxy (MOVPE) and flow-rate modulation epitaxy (FME), in-situ monitoring of epitaxial growth using surface photo-absorption (SPA), heterojunction bipolar transistors (HBTs), and so on. His current interests are epitaxial growth of nitride semiconductors and nitride semiconductor devices. He is an associate editor of Japan Society Applied Physics and JSAPI, and a member of the Japan Society of Applied Physics, the Institute of Electronics, Information and Communication Engineers, and Materials Research Society.
