A fibre with a large value of V. supports many modes.‚ however for V < 2.4 all modes except for the HE11 mode reach cut-off. That fibres support a single-.mode and are called single-.mode fibre‚ supporting only the HE11 mode‚ familiar as the fundamental mode of the fibre.. The lowest order mode HE11 is denoted LP01. The single-.mode situation is determined by the value of V. at which the

(UK)PhD(Cal.‚USA) Abstract Vortex spinning can be viewed as a refinement of jet spinning‚ or a natural development in fasciated yarn technology. As in all other fasciated yarns‚ the structure of vortex yarn consists of a core of parallel fibres held together by wrapper fibres. This has been revealed by examining an untwisted vortex yarn sample under the Scanning Electron Microscope. Subsequently‚ the physical properties of vortex and air-jet yarns produced from different polyester cotton blends were

Vahala California Institute of Technology‚ Mail Stop 128-95‚ Pasadena‚ California 91125‚ USA (e-mail: vahala@caltech.edu) Optical microcavities confine light to small volumes by resonant recirculation. Devices based on optical microcavities are already indispensable for a wide range of applications and studies. For example‚ microcavities made of active III–V semiconductor materials control laser emission spectra to enable long-distance

1.7 Cisco 2 References Support[edit] Some products were marketed around 2005 with the term C-NIC which combined iSCSI storage functionality with Gigabit Ethernet. Later products used the marketing term converged network adapter (CNA)‚ combining Fibre Channel over Ethernet with 10 Gigabit Ethernet‚ for example. Brocade[edit] Brocade Communications Systems offers two types of CNAs‚ with PCI Express generation 2.0 interfaces. The only difference between the two models are the number of interfaces
