International Conference on Optical Communications and Networks (ICOCN) serves as an international forum for researchers involved in all aspects of optical communications and networks. ICOCN is held annually, and is sponsored by IEEE Photonics Society. All accepted papers will be published in the conference proceedings and will be included in IEEE Xplore (indexed by EI Compendex). ICOCN2015 will be held on July 3-5, 2015 in Nanjing, China. We would like to invite you to participate in this conference, to share your recent research results in optical communications and networks, and to take the opportunity to interact with researchers in the area. We look forward to seeing you at ICOCN2015, Nanjing!
