We introduce a proof-of-concept, optically controlled, optical switch based on the monolithic integration of a surface-illuminated photodetector and a waveguide electroabsorption modulator. We demonstrate unconstrained wavelength conversion over the entire center telecommunication wavelength band ~C band! and optical switching up to 2.5 Gbit/s with extinction ratios exceeding 10 dB. Our approac...

The problem of designing telecommunication switching cabinets is referred to as the q-model configuration problem. The objective is to design and configure switching cabinets to match the pattern of customer demand such that the total number of insertions required to manufacture a given set of orders is minimized. We make refinements to existing heuristic procedures developed to solve the q-mod...

This paper aims to investigate the influence of the interaction between customer satisfaction and switching barriers on customer retention in mobile telecommunication services. The detailed factors regarding switching barriers are classified based on the related literatures. Furthermore, the hierarchical regression analysis is used to analyze the extent to which the factors affect customer rete...

A photonic fast packet switch is proposed for low-latency intra-node routing in high-speed optical networks. Applications are demonstrated in telecommunication and parallel computer environments. The switch fabric is based on integrated directional-coupler technology. It has low complexity and is geometrically suitable for realestate e cient single substrate implementation. The switching archit...

This document describes a method for controlling two specific types of Ethernet switching via Generalized Multi-Protocol Label Switching (GMPLS). This document supports the types of switching corresponding to the Ethernet services that have been defined in the context of the Metro Ethernet Forum (MEF) and International Telecommunication Union (ITU) G.8011. Specifically, switching in support of ...

I. DEFINITION OF PROBLEM In current conditions of dynamic development of various approaches of the analysis and synthesis of the telecommunication networks integrated into information and telecommunication technology [1-5] there are questions of elaboration and application of the general methods of ensuring service quality based on allocation of separate classes of quality and realization of ma...

We theoretically discuss all-optical switching at the Fano resonances of subwavelength gratings made of a chalcogenide glass (As(2)S(3)). Particular attention is devoted to the case in which the grating possesses extremely narrow slits (channels ranging from a∼10 nm to a∼40 nm). The remarkable local field enhancement available in these situations conspires to yield low-threshold switching inten...
