(Agrawal et al. [37]) common process flow as well as a Mach–Zehender wavelength converter that would serve as the foundation of an integrated nonlinear optical thresholding device [36]. Such integrated chip solutions, when sufficiently developed and successfully refined, would significantly contribute to further progress in OCDMA. "

    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: This paper investigates merits and challenges of all-optical routers. All-optical routers can exploit the wavelength domain not available in electronic routers to overcome the lack of optical buffers, and to realize compact ultralow power systems.

    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.
