We demonstrate the production of a well depleted mid-IR continuum with a spectral range between ~0.9 - 2.5 mum using a tellurite wagon wheel microstructured fiber and a pump source at 1.5 mum.
Artificial boundary conditions for LES away from the wall have been developed with the hope of avoiding the problem of grid refinement in the wall region of the LES. In the particular example of channel flow, the main idea is to replace the natural no-slip boundary conditions (at y = 0) by artificial boundary conditions at y = y1 > 0. The one-point… (More)
We report the fabrication of a square core jacketed air-clad fiber with a top-hat near-field intensity profile. Using this fiber we have successfully produced square shaped ablation marks in ITO without complex beam shaping optics
Preliminary work has shown that the bending losses of large-mode-area holey fibers can be improved by modifying the hole configuration (Mortensen et al. (2003)). For the first time, we accurately quantify the advantages of this technique.
We review our recent progress in the area of microstructured fiber design, fabrication and applications with particular emphasis on the control of both the nonlinearity and dispersion.
The upper limits imposed by bend loss on practical mode size in single-mode holey and step-index fibers are identified for a range of wavelengths. Using these results we quantify the advantages offered by holey fibers.
We review recent advances in the development of HF technology and describe various practical applications of the technology in the areas of nonlinear and active fiber devices.
We report the fabrication of a spun holey optical fiber. Measurements of differential group delay (DGD) confirm that significant reductions in polarization mode dispersion (PMD) can be readily achieved using this approach.
The large number of grid points required in the near-wall region of attached turbulent boundary layers is the chief obstacle to applying large eddy simulation (LES) to many flows of engineering interest. Current subgrid scale (SGS) models do not accurately model the subgrid scale Reynolds stresses (Baggett et al. 1997, Jiménez & Moser 1998). Thus, if the… (More)
