    ABSTRACT: Code-division multiple-access (CDMA) has flourished as a successful wireless networking technology in mobile cellular telephony, and wireless local area networks (LAN) such as the unlicensed industry, science, and medicine (ISM) bands. The commercial exploitation of the benefits of CDMA raises the question as to whether optical code-based communications offer significant benefits to an optical network and what are the technologies that enable code-based optical networks. Recent investigations of optical CDMA (OCDMA) strategies have addressed this question through numerous laboratory-based test-bed studies of multiuser link and recent experimental field trials conducted on in-the-ground fiber. OCDMA requires its own physical layer technologies that are distinctly different from widely pursued wavelength-division-multiplexed (WDM) all-optical networks. Simulations of multiuser performance predict ultimate link capacity and the performance of broadcast and select synchronous nets with strong central management as well as asynchronous architectures with reduced centralized management.

    ABSTRACT: We overview and summarize the progress of the spectral phase encoded time spreading (SPECTS) optical code division multiple access (O-CDMA) technol-ogy. Recent progress included a demonstration of a 320 Gbit/ s 32-user 10 Gbit/ s all-optical passive optical network testbed based on the SPECTS O-CDMA technology and a theoretical prediction of the spectral efficiency at 100% and above. In particular, InP-based integrated photonics allows imple-mentation of SPECTS O-CDMA transmitters and receivers monolithically in-tegrated on a chip. The integrated InP chip technology not only allows robust and compact configurations for practical and low-cost O-CDMA network de-ployments but also offers code reconfigurations at rapid rates for secure com-munication applications. © 2007 Optical Society of America OCIS codes: 060.4080, 060.4510, 130.3120.

    ABSTRACT: This paper reviews the energy efficiency of optical-packet-switching (OPS) systems in comparison with electronic packet switching and hybrid packet switching in the context of future networks. The paper will first discuss the energy efficiency metrics that should include considerations for life-cycle analysis, applications, and network-wide goodput. The state-of-the-art electronic packet switching router is currently energy-limited in scalability as it is difficult to implement a router with more than 1 MW power consumption. The OPS router that imitates electronic router's store-and-forward schemes is expected to suffer poor energy efficiency due to the complexity in the high-speed control plane necessary to control many optical buffer stages. The hybrid optical router achieves easier buffer management but its energy efficiency is still limited by the store-and-forward approach. The OPS router based on all-optical contention resolution without relying on store-and-forward method can keep the control plane very simple and achieve very high energy efficiency. Network-wide performance and energy efficiency in the context of generalized multiprotocol label switching (GMPLS)- and multiprotocol label switching (MPLS)-based networking are also discussed.
