Service providers around the globe have begun commercializing triple play services to better compete with cable and satellite operators. While this is helping boost average revenue per user (ARPU), it is placing unprecedented stress on the traditional high-speed Internet infrastructure. This article examines the issues of deploying triple play services ...

This paper introduced the consolidating services over a common IP/MPLS infrastructure only addresses the delivery challenges MSO (multiple system operators) face as they work to address residential and commercial service requirements. To address service quality and reliability issues, MSOs must look beyond the uderlying infrastructure to the routers that route ...

DESIGN AND CHARACTERIZATION OF A NOVEL ICP PLASMA TOOL FOR HIGH SPEED AND HIGH ACCURACY DRIE PROCESSING
- Launay N.
Advanced Deep Reactive Ion Etching (DRIE) with high etch rates (30 ?m/min) is achieved by using an etching system with a novel ICP (Inductively Coupled Plasma) source and substrate holder (chuck). Waferstepper dual side lithography (front- to backwafer overlay ? 500 nm) is used to fabricate electrical overlay test structures ...
THE PREPARATION AND APPLICATION OF CRUDE CELLULASE FOR CELLULOSE-HYDROGEN PRODUCTION BY ANAEROBIC FERMENTATION
- Fan S-Q
Strategies were adopted to cost-efficiently produce cellulose-hydrogen by anaerobic fermentation in this paper. First, cellulase used for hydrolyzing cellulose was prepared by solid-state fermentation (SSF) on cheap biomass from Trichoderma viride. Several cultural conditions for cellulase production on cheap biomass such as moisture content, inoculum size and culture time were ...

WiMax, a fourth-generation wireless-access technology, has made significant progress both in the standard forums and with wireless network carriers. To ensure service continuity to a legacy end user, it is important for a WiMax mobile device to interwork with existing third-generation access networks before it is uniquely and ubiquitously deployed. ...
A SURVEY OF RESEARCH ON THE APPLICATION-LAYER TRAFFIC OPTIMIZATION PROBLEM AND THE NEED FOR LAYER COOPERATION
- Gurbani V.
- Hilt V.
A significant part of Internet traffic today is generated by peer-to-peer applications, used traditionally for file sharing, and more recently for real-time communications and live media streaming. Such applications discover a route to each other through an overlay network with little knowledge of the underlying network topology. As a result, ...
CARRIOCAS PROJECT: TOWARDS CONVERGED INTERNET INFRASTRUCTURES SUPPORTING HIGH PERFORMANCE DISTRIBUTED APPLICATIONS
- Audouin O.
- Verchere D.
The CARRIOCAS project studies and implements a high bit rate optical network capable of accommodating the requirements of data-intensive, high-performance distributed applications, in terms of bandwidth, quality of service guarantees, dynamic and automated service provisioning. The investigations are carried out under the constraints of supporting the applications on converged network ...

We demonstrate a one-dimensional grating coupler in silicon nitride with a 67-nm 1-dB bandwidth, the largest reported for a grating coupler butt-coupled to standard single-mode fiber. The peak coupling efficiency is -4.2dB. It requires no partial etch and requires only 0.6-?m fabrication resolution.
REAL-TIME IMPLEMENTATION OF DIGITAL SIGNAL PROCESSING FOR COHERENT OPTICAL DIGITAL COMMUNICATION SYSTEMS
- Corteselli S.
- Kaneda N.
- Leven A.
Digital signal-processing-based coherent optical communication systems are widely viewed as the most promising next-generation long-haul transport systems. One of the biggest challenges in building these systems is the implementation of signal processors that are able to deal with signaling rates of a few tens of giga-samples per second. In this ...

While InGaAs absorption material has been used for various applications up to 1.6-?m wavelength, specific designs for low-level detection have become of main interest using high responsivity and low-dark-current detectors. By adding an avalanche multiplication layer to form an avalanche photodiode (APD) using the Separated Absorption and Multiplication (SAM) structure, ...
