“…However the large nonlinear absorption through two photon absorption limits the operation of these devices at the telecom wavelengths. A lot of research has been done on other materials which have less or no two photon absorption such as chalcogenide glasses [6]. Recently, SOI hybrid slot waveguides have been demonstrated by using a polymer cladding as the nonlinear material [7].…”

Abstract-We study self phase modulation in submicron amorphous silicon-on-insulator waveguides. We extract both the real and imaginary part of the nonlinear parameter γ from a 1 cm long waveguide with a cross-section of 500x220nm 2 . The real and imaginary part of the nonlinear parameter are found to be 767W -1 m -1 and 28W -1 m -1 respectively. The figure of merit (FOM) is found to be 3.6 times larger then the FOM in crystalline silicon (c-Si).

“…More precisely, we design the well-known Mamyshev regenerator based on the self-phase modulation in normal dispersion regime followed by an offset spectral filtering and we characterize its transfer function [32]. In order to obtain a steplike power transfer function we combined 2 meters of chalcogenide fiber with a fiber Bragg grating band pass filter [33,34]. Figure 7 shows the experimental set-up.…”

Abstact:The aim of this paper is to present an overview of the recent achievements of our group in the fabrication and optical characterizations of As 2 S 3 microstructured optical fibers (MOFs). Firstly, we study the synthesis of high purity arsenic sulfide glasses. Then we describe the use of a versatile process using mechanical drilling for the preparation of preforms and then the drawing of MOFs including suspended core fibers. Low losses MOFs are obtained by this way, with background level of losses reaching less than 0.5 dB/m. Optical characterizations of these fibers are then reported, especially dispersion measurements. The feasibility of all-optical regeneration based on a Mamyshev regenerator is investigated, and the generation of a broadband spectrum between 1 µm and 2.6 µm by femto second pumping around 1.5 µm is presented.

“…These high-precision methods are essential when simulating pulse propagation through highly non-linear fibre. Chalcogenide glass fibres have been proposed as the HNLF within the SBF regenerator (Fu et al 2005), which may have a nonlinear parameter of greater than 1,000 (W km) 1 , which is greater than that of standard silica fibres by more than a factor of 500. The SBF regenerator has received a relatively broad investigation into its range of operation and optimisation.…”

1higher, linear and non-linear fibre impairments become prominent factors affecting the signal quality. Thus, new techniques in both physical layer and network layer are necessary for mitigating impairments to accommodate high-speed traffic (Tomkos et al. 2002). On the other hand, the flexibility of modern networks with dynamic and distributed management, where lightpaths can be dynamically and automatically assigned end-to-end, increases the risk of changing path conditions that affect signal quality and consequently quality of service (QoS) over the lifetime of a connection as well as for subsequent connection set-up requests (on-demand routing and wavelength assignment -RWA). For traditional connection provisioning an ideal physical layer, ignoring transmission impairments (Chlamtac et al. 1992) could be assumed because the implicit per hop regeneration (optics-to-electronics-to-optics conversion -O/E/O) compensated signal impairments hop-by-hop in a rather static manner (section commissioning). For end-to-end all-optically switched connections using photonic cross-connect switches (PXC), the conditions change and common practice is not applicable. Anyhow, intelligent connection provisioning is an important traffic engineering problem, and minimising operational cost as well as efficiently utilising network resources is the main driver. In this context, it seems important to have flexible routing protocols that take into consideration the most relevant physical impairments, and are able to exchange messages with their values as part of the route information with others. This condition, if definitely used to calculate routing, will surely assure better success in data delivery over the network (Huang et al. 2005). Irrespective of the control architecture chosen by an operator of an optical network, the included control plane (in charge of setting up and tearing down optical circuits; also known as lightpaths) needs to have a proper set of tools to satisfyingly deal with physical impairments. The most essential tools are: optical signal monitoring, signal processing and impairment compensation techniques (each all-optically and/or electrically). With the help of these tools, it is possible to predict the QoT (quality of transmission) attainable for a lightpath at a given time (i.e. the latest network-wide monitoring instant), and the control plane can route requests across the network
