Asia Communications and Photonics Conference (ACP) is the premier conference in the Asia-Pacific region on photonics and relevant technologies including photonic materials and devices, communication and network technologies, sensing technologies, biophotonic technologies, illumination technologies, photovoltaic technologies and other photonic technologies regarding energy issues. ACP has been held annually tracing back to 2001 and jointly sponsored by three USA societies (OSA, SPIE, and IEEE Photonics Society) and two Chinese societies (COS and CIC). ACP'2013 will be held in Beijing, China, on November 12-15, 2013. Co-located and jointly organized will be IPOC'2013 - the International Conference on Information Photonics and Optical Communications in 2013. IPOC is a biennial conference initiated and sustained by the State Key Laboratory of Information Photonics and Optical Communications (at Beijing University of Posts and Telecommunications, briefly BUPT). The first IPOC, being fully supported by Nanyang Technological University, was held in 2011 in Singapore. For both the two conferences of this year, the local organizers are two state key laboratories of China, namely, the State Key Laboratory of Information Photonics and Optical Communications as mentioned above and the State Key laboratory of Fibre and Cable Manufacture Technologies (at Yangtze Optical Fibre and Cable Company Ltd., briefly YOFC). Great supports will be given by BUPT, YOFC, Tsinghua University, Peking University, Beijing Jiaotong University and Institute of Semiconductors, Chinese Academy of Sciences. Dear colleagues and friends from all over the world, join us, join this special event! You are warmestly welcome and our gathering in Beijing will be a precious and pleasant experience of everyone!
