Conference name: 4th International Conference on Optical Communication Systems (OPTICS 2013)Venue: Reykjavík, IcelandEvent Date: 29-31 July, 2013The purpose of OPTICS 2013, the International Conference on Optical Communication Systems, is to bring together researchers, engineers and practitioners interested on any of the optical communication components of an optical communication system, or the system itself. An optical communication system consists of a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.Optical fiber is currently the main means for high-rate transmission in communication networks. In the last years, there is a great deal of ongoing research efforts that span the entire protocol stack of optical networks, with representative areas being architecture of optical components, optoelectronics, wavelength routing, energy efficiency, Quality of Service, hybrid optical-wireless networks etc.CONFERENCE TOPICS    Integration of Optical and Wireless Networking    Design, Control and Management of Optical Networks    Energy Efficiency in Optical Networks    Passive Optical Networks    High Speed optical LANs and Gigabit Ethernet    Lasers and Photonic Components    New Architectures for Optical Routers and Switches    New Optical Fiber Technologies    Optical Modulation and Signal Processing    Optical Access Networks    Optical Networks Performance Modelling    Optical Networks to Support Cloud Computing    QoS.
