This paper describes experimental and simulation results of the optical packet experimental routing architecture (OPERA) project. The OPERA network is based on a novel optical network interface router design that is optically regenerative and supports optical internet protocol related functions including label swapping, packet routing and forwarding operations and wavelength reuse. Routing is b...

We present an Integer Linear Program based algorithm and a K shortest path based heuristic algorithm for solving the Routing and Wavelength Assignment problem in All Optical Networks with Limited Wavelength Conversion. These algortihms are executed on a random mesh National Science Foundation Network(NSFNET). Their performances are compared.

We compare theoretically the performance capabilities of Fabry-Perot and Gires-Tournois resonators when used for adiabatic wavelength conversion. It is shown that the Gires-Tournois device will exhibit superior performance and is able to convert the wavelength of optical pulses with >74% efficiency while nearly preserving their temporal duration.

A design of a nonblocking, all-optical lightpath concentrator using WOC and WDM crossbar switches is presented. The proposed concentrator is highly scalable, cost-efficient, and can switch signals in both space and wavelength domains without requiring a separate wavelength conversion stage.

Wavelength-tunable deep-ultraviolet (DUV; ~200–300 nm) and vacuum-ultraviolet (VUV; ~100–200 nm) lasers are needed in fields such as lithography1, medicine1 and spectroscopy2. However, many laser sources in this wavelength range, including excimerand ion-based DUV and VUV lasers, are complex and expensive to manufacture and operate because of their high power consumption, short lifetime, low ef...

We demonstrate an optical approach to control fourwave mixing (FWM) conversion bandwidth based on gaintransparent stimulated Brillouin scattering (SBS) in fiber. By introducing self-compensation of optical gain/loss with frequency-locked SBS pump and Stokes waves, the FWM phase matching condition can be flexibly controlled through SBS induced refractive index change without affecting the signal...

We propose a super-channel flexible wavelength division multiplexing (WDM) receiver architecture. The receiver, which requires no optical filtering, only a pair (I and Q phases) of coherent optical detectors, and an electrical receiver system, can simultaneously recover multiple wavelength-multiplexed channels using cascaded optical and electrical down-conversion. The receiver data capacity inc...

Introduction The optical-label switching (OLS) technology supports transparent all-optical routing and sophisticated network functions by processing the short label in the electronic domain while leaving the data payload in the all-optical domain [1]. In this way, the routing is independent of the payload data format and bit rate. Moreover, with the help of electronic circuit, the router can su...

Wavelength division multiplexing (WDM) is attractive for the infrastructureof the next generation Internet, since it supports huge bandwidth by multiplexingseveral wavelengths into a single optical fiber. In order to transmit Internet dataover WDM networks, network architectures with photonic technologies, such aswavelength routing, optical burst switching (OBS), and optical pac...

With wavelength division multiplexing (WDM) several optical signals can be transferred in a single optical ber [6][7]. This technology allows more e cient use of the huge capacity of an optical ber but also poses new network design and management problems, especially when wavelength conversion is not possible in the nodes. In this paper we consider the routing and wavelength assignment problem ...
