Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G07G 1/00

US Classification:

705010000

Abstract:

A system, method and apparatus are provided for designing and evaluating a supply-chain architecture and strategy, and communicating the architecture to concerned parties. The supply chain is designed by combining business strategies and analytical modeling in a well-defined process. Key product and market attributes are combined with defined supply-chain processes and strategies, to identify a preferred supply chain architecture and strategy. Feedback from the concerned parties is collected, and modifications are made iteratively to the supply chain architecture and strategy, based on the collected feedback.

Abstract:

An electronically switchable multiwavelength laser system comprises a lasing medium capable of generating a beam having at least two different wavelengths, an anisotropic birefringent component in optical alignment with the medium for refracting the beam into spatially separate polarized rays containing both wavelengths, and another electrically controllable anisotropic electrooptically active element, such as a Pockels' cell, having electrodes aligned with the respective rays and selectively energizable to block either ray to permit the laser to oscillate at the wavelength and polarization of the unblocked ray. The laser system includes highly reflective and partially transmissive mirrors defining the laser cavity and assisting in wavelength discrimination, the birefringent component and Pockels' cell being disposed in series between the lasing medium and the highly reflective mirror. Another embodiment comprises a tunable laser having a continuum output over a band of wavelengths, the Pockels' cell being selectively energized with a precise voltage which enhances lasing at the selected wavelength and inhibits operation at other wavelengths.
