Joint Research
We will demonstrate a long-haul Tbit/s/ch
transmission, in which the bit rate is increased to 1.28 Tbit/s either with polarization multiplexing
or DQPSK modulation and further to 2.56 Tbit/s by combining these two schemes. We take full
advantage of ultrafast optical devices developed in HHI, DTU, and ORC to realize such an
ultrahigh-speed transmission. We will also provide our optical signal processing technologies to
overseas collaborators to promote their research activities in partner countries.
Seminar
In 2010, we plan to organize gInternational Symposium on Ultra-high Capacity Optical Communication
and Related Optical Signal Processing and Devicesh in Copenhagen, Denmark, which will be
hosted by DTU. Based on the success in ISUPT 2009, we expand the scope to include signal
processing and device technologies, and invite eminent researchers from worldwide. This symposium
is held as a satellite meeting of ECOC 2010, which is one of the largest international conferences
on optical communication, and it will be a good oppornunity to make an appel of our collatorative
research activities to worldwide. We will also continue to organize gOptical Science Colloquiumh
as well as gOptical Science and Technology Forumh in Tohoku University to enhance interactions
between different areas of optical sciences.
Researcher Exchanges
More than 20 members of this program will visit DTU from Japan to attend the international symposium
and accelerate the research activities through discussion and collaboration with each other. We will also
send researchers to attend ECOC, OFC, and CLEO to present the latest advances in Japan and share the
research progress with overseas collaborators.
Achievements in 2009
We organized gInternational Symposium on Ultrafast Photonic Technologiesh (ISUPT2009) on
August 4-5, 2009 at Tohoku University. The symposium consisted of 22 invited presentations by
eminent speakers worldwide in the field of ultrafast photonics. 137 researchers participated in the
symposium, and the latest advances and future directions of this field were intensively discussed.
In addition, gOptical Science Colloquiumh was held three times at Tohoku University aimed at
stimulating discussions and communications among researchers and students, which made a large
contribution to enhance abilities in presentation and discussion of young researchers. Furthermore,
joint research on ultrahigh-speed transmission was carried out with DTU. Through the collaboration
with a visiting researcher from DTU, 640 Gbit/s-525 km DPSK transmission was successfully
demonstrated for the first time. 18 researchers visited overseas and strengthened communication
with overseas collaborators through international conferences and workshops. From these achievements,
the objective of the present research exchange is making a steady progress.
