A wavelength assignment method for distributed wavelength-routed networks using a circular wavelength-list

2nd International Conference on Broadband Networks, 2005., 2005
In a distributed wavelength-routed network, a lightpath request is blocked when its assigned wavelength is already occupied by another lightpath request. Conventional studies assume that a wavelength for the lightpath is selected randomly in the distributed lightpath setup method.

On the optimal placement of wavelength converters in wavelength-routed networks

Proceedings. IEEE INFOCOM '98, the Conference on Computer Communications. Seventeenth Annual Joint Conference of the IEEE Computer and Communications Societies. Gateway to the 21st Century (Cat. No.98CH36169), 2002
We consider the problem of optimally placing a given number of wavelength converters on a path to minimize the call blocking probability. Using a simple performance model, we first prove that uniform spacing of converters is optimal for the end-to-end performance when the link loads are uniform and statistically independent.

Connectivity and sparse wavelength conversion in wavelength-routing networks

Proceedings of IEEE INFOCOM '96. Conference on Computer Communications, 2002
Wavelength-routing networks offer the advantages of wavelength re-use and scalability over broadcast-and-select networks and are therefore suitable for wide area networks (WANs). We study the effects of topological connectivity and wavelength conversion in circuit-switched all-optical wavelength-routing networks.

Wavelength assignment in waveband switching networks with wavelength conversion

IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
Waveband switching (WBS) wherein wavelengths are grouped into bands and switched as a single entity can reduce cost and complexity of switching nodes by minimizing the port count. In this paper, we study the effect of wavelength conversion on the performance of WBS networks with reconfigurable multi-granular optical cross-connects (MG-OXC) to satisfy ...

Time-Domain Wavelength Interleaved Networking with Wavelength Reuse

Proceedings IEEE INFOCOM 2006. 25TH IEEE International Conference on Computer Communications, 2006
Time-domain Wavelength Interleaved Networking (TWIN) is a cost-effective network architecture that can provide fine-grained, flexible connectivity using passive optics in internal nodes. Each wavelength is dedicated to carry traffic to a single node. We introduce TWIN with wavelength reuse (TWIN-WR), an extension of TWIN that allows the number of nodes

Selection of operating wavelength‐pair for two‐wavelength microspectrophotometry

American Journal of Anatomy, 1976
AbstractThe two‐wavelength method is the microspectrophotometric method of choice for thick specimens. Its accuracy is dependent on the accuracy of selection of the operating wavelength‐pair. The “slope zero test,” offered as a check upon the accuracy of this selection (Garcia and Iorio, ′66) is shown to be invalid by analysis of experimental data, by ...

Modulating Short Wavelength Fluorescence with Long Wavelength Light

Journal of the American Chemical Society, 2014
Two molecules in which the intensity of shorter-wavelength fluorescence from a strong fluorophore is modulated by longer-wavelength irradiation of an attached merocyanine-spirooxazine reverse photochromic moiety have been synthesized and studied. This unusual fluorescence behavior is the result of quenching of fluorophore fluorescence by the thermally ...

Hybrid wavelength and sub-wavelength routed optical networks

GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002
Although wavelength routing has many advantages, it also has some inflexibilities. For one thing, the routing granularity is large, which could lead to waste of bandwidth when demand is fractional in the units of wavelengths. For another, full connectivity in a large network puts a serious stress on the number of wavelengths required in the network. To
