Awarded Paper:
M. Yamagiwa, A. Komatsu, Y. Awatsuji, and T. Kubota, "Observation and analysis of the propagating femtosecond light pulse train generated from an integrated array illuminator using light-in-flight recording by holography," IEEE Journal of Selected Topics in Quantum Electronics vol.11, pp.510-518 (2005).

The Tokyo Denki University Science Promotion Fund established the award in 1977, honoring the achievements of the first president Prof. Yasujiro Niwa, for young researchers across Japan in the field of electronic communications. The award goes to up to two authors who have presented excellent papers, from among graduate students and those who have completed graduate studies within the last two years in the field of electronic communication engineering including information engineering. The Fund requests 143 academic research institutes across the country, mainly graduate schools at public and private universities, to recommend candidates.
The awarded paper discusses holographic recording using femtosecond laser. The paper observed the propagation of light pulse generated from an optical device called an array illuminator in the form of a motion picture. It then analyzed the characteristics of the reconstructed image in detail. This technology is expected to be applied to the evaluation of terabit-class ultra-wideband optical communications as well as observation and clarification of ultrafast phenomena.
