Chalcogenide glasses are based on a mixture of chalcogen elements (Sulphur, Selenium and Tellurium) and other elements such as Arsenic, Germanium, Antimony or Gallium. Compared to silica glasses, they offer several distinctive optical properties such as their transmission window which extends far into the infrared spectral region (up to 25μm for telluride glasses). Chalcogenide glasses also exhibit an extremely high nonlinear index coefficient n2 that can be two or three orders of magnitude greater than in silica at 1.55 μm. These nonlinear properties can be further enhanced by drawing these glasses into Chalcogenide Photonic Crystal Fibers (CPCF) due to the possibility of designing such fibers with a very small core diameter [1–3]. Since 2004, PERFOS and the laboratory "Glass and Ceramics" of Rennes University (EVC) have worked together to develop CPCFs [4–6] and are currently investigating a new method to fabricate chalcogenides preforms based on the glass casting process.

Introduction Over the past several decades there has been growing interest in the development of devices for optical wavelength conversion. In Raman converters, a long-wavelength Stokes input is in the presence of a pump transformed into a short-wavelength anti-Stokes output via a Raman-resonant third-order nonlinear process called coherent anti-Stokes Raman scattering (CARS) [1]. In Kerr-based parametric converters, a signal input is in the presence of a pump converted to an idler output via the third-order nonlinear process of non-resonant four-wave-mixing (FWM) [2]. Both types of conversion can occur in silicon waveguides, and as such have great potential for application in optical communication systems.

We propose a polarization-multiplexed iterative polar quantization (IPQ)-based LDPC-coded-modulation scheme suitable for beyond 400 Gb/s serial optical transmission. The component LDPC codes are designed using modified progressive edge-growth (MPEG) algorithm. The proposed scheme employs 32-IPQ-based-modulation.

Data centers have been evolving to meet the requirements for scale, and flexible service delivery with the most efficient resource utilization (CapEx), and operational simplicity (OpEx), including notably power management (which is important for both CapEx and OpEx). In many respects, the data center architecture has been closely following the computing paradigm, moving from a centralized design in the era of mainframe computing, to decentralized designs with the advent of client-server and distributed computing [1]. The scaling of these decentralized designs however has been increasingly challenging due to the interconnectivity and fiber-management needs (Figure 1), leading to complex configurations (top-of-rack, end-of-row, environmental, etc.) in order to meet environmental constraints. At the same time the cost for power and cooling has been dramatically increasing, currently often exceeds the actually server cost [1, 2]. Significant advancements in: 1) stateless computing, 2) consolidated switching fabric, combining both Ethernet and Storage transport, and 3) photonics for 10/40/100GE interconnectivity technologies, have recently enabled the evolution towards a new converged data center architecture. Figure 2 shows the main layer of this new architecture. An access switching layer interconnecting the different applications servers, is aggregated in a consolidated core switching layer that could also combine the important (typically also hierarchical) storage infrastructure (using the new FCoE standard). The application virtualization, and consolidated switch fabric advance significantly the operational efficiency of the ever increasing need for computationally intensive applications. At the same the advancements in the price performance of 10GE and emerging 40 and 100 GE optical interconnections have dramatically improved the capacity scalability, and infrastructure cost (CapEx). These innovations have also enabled significant power-efficiency improvements. For example the CXP optics modules would offer 100GE interconnectivity (up to 2km) with more than 10x improved power consumption when compared with the 1.2 Watts per Gb/s of the GBIC GE technology [3].
