1. Commission Activities
 Sessions by Commission D at AP-RASC 2013, where conveners are contributed from Japan.
D1: Space Photonics
Ren Liu, Kazuo Hotate
DC: Radio-over-fiber Systems and Technologies
Hai-Han Lu, Toshiaki Kuri
DJ1: Microwave Integrated Circuits
Tian-Wei Huang, Shigeo Kawasaki
DJ2: Terahertz-wave Technologies
Ci-Ling Pan, Tadao Nagatsuma
 Sessions for URSI-GASS 2014
Two sessions proposed by Commission D of Japan have finally been approved;
1) Broadband Ubiquitous Network with Wired and Wireless convergence (Katsumi Iwatsuki,Yuichi Kado, Katsutoshi Tsukamoto) scheduled on August 19, 2014.
2) Trends in THz Communications (Tadao Nagatsuma, Ci-Ling Pan, Thomas Kuerner)scheduled on August 22, 2014.
In addition to the above THz-related session, Chair of Commission C asked us to jointly
organize a session on “Ultra-high bit rate radio communications (TeraHertz and 60 GHz)”, andnot only we agreed to the proposal, but also we decided to jointly organize the above session 2)
by inviting the fourth convener from Commission C.
 URSI-D Electronics & Photonics Workshop
Planning has started to hold a domestic workshop organized by Commission D. One of the newtrials and/or challenges in this workshop will be e-conference-style together with a main venueof Osaka University (tentative).

2. Domestic activities related to areas covered by Commission D
Technical Committee on Microwave Photonics (IEICE):
Following technical meeting was held on specific subjects including regular contributions:
April 26, 2013 (Tokyo); Wireless network systems (M2M, cloud, cognitive, etc.)

1Technical Committee on Terahertz Applications Systems (IEICE):
Following technical meeting was held on specific subjects:
May9,2013(Atsugi);

Emerging

technologies

andapplications

using

undeveloped

electro-magnetic waves, including photonic crystals, graphene, etc. This meeting was jointly heldwith Technical Committee on Electronics Simulation.

3. International activities related to areas covered by Commission DInternational Workshop on Optical Terahertz Science and Technology 2013 (OTST2013):
The conference was held from 1-5 April 2013 consisting of 4 days technical sessions in Kyoto,
Japan. Papers cover topics on terahertz sources, detectors, and applications for measurement,
imaging, spectroscopy, and communications.
Asia-Pacific Microwave Photonics Conference 2013 (APMP2013):
The conference was held from 22-14 April in Gwangju, Korea. Main topics were microwave
photonic devices, THz devices and their applications such as radio-over-fiber systems, terahertz
communications/sensing systems, microwave photonic signal processing, etc.
International Microwave Symposium 2013 (IMS 2013) :The conference was held on 2-7 June in Seattle. This year, number of papers on terahertz-related
field has exceeded that of 60-GHz millimeter waves. In particular, two full day workshops wereorganized; “Signal Generation, Amplification and Detection at THz Frequencies”, and“Technologies for THZ Integrated Systems”, where Si-CMOS based THz technologies have started
to become a main stream.
