In response to the need for higher flexibility in optical networks, a Generalised Multi-Protocol Label Switching (GMPLS) protocol suite is currently under standardisation. However, in these standards a Label Switched Path (LSP) hierarchy is defined that only considers circuit-switched optical networks. This paper aims at broadening the scope of this hierarchy to more advanced optical networking...
Simultaneous optical parametric oscillation and intracavity second-harmonic generation based on a hexagonally poled lithium tantalate is reported. Both the optical parametric oscillation and the cascaded noncollinear second-order harmonic generation processes reach a high efficiency. A variety of possible self-doubling optical parametric oscillation processes indicate this hexagonally poled lit...
The purpose of this paper is to present an optical test platform for high bit rate DWDM systems. The developed platform is transparent and independent of the format of the optical signals, number of WDM channels and transmission ratios. It enables the laboratory simulation of real systems with multi-wavelength and high bit rates optical networks.
Aetna considers in-vivo analysis of colorectal polyps (e.g., chromoendoscopy, confocal laser [fluorescent] endomicroscopy [including Cellvizio probe-based confocal laser endomicroscopy], endocytoscopy, EVIS EXERA 160A System, fiberoptic analysis, multi-band imaging, narrow-band imaging optical chromocolonoscopy, Optical Biopsy System, Pentax Confocal Laser System, and WavSTATTM Optical Biopsy S...
Recently, the quaternary InGaAsN alloy system has attracted a great deal of attention due to its potential application in devices such as next generation multi-junction solar cells and optoelectronic devices for example laser diodes for optical communications in IR region. In this paper, we have investigated the role of nitrogen on the improvement of optical efficiency in InGaNAs nanostructur...
The nonlinear optical properties of carbon nanotubes (CNTs) have been studied by using the Z-scan technique. Experiments are performed by CW second harmonic of Nd-YAG laser at 532 nm wavelength with a power of 40 mW. The samples are synthesized by the chemical vapor deposition (CVD) method in the presence of Nickel and Nickel-Cobalt catalysts. In this work, for the first time, effect of the typ...
