A technique for structuring FORTRAN programs is reviewed, and a preprocessor is described which converts pure structured code into standard FORTRAN. It is claimed that structured FORTRAN is generally easier to read and write than unstructured FORTRAN. Actual examples are given of structured FORTRAN and results of preprocessing.
The effects of Er-Er pairs on the characteristics of Er-doped fiber amplifiers are analyzed theoretically. Pairs are found to have little effect on the amplifier optimum length, signal saturation power, and noise figure (at constant gain) but to cause significant reduction in the gain, even at residual levels, quantitatively consistent with fiber laser(More)
We propose to produce a superfluorescent fiber source (SFS) with a linearly polarized output by inserting a discrete polarizer near the middle of a polarization-maintaining Er-doped fiber. We show that with a relatively low-loss polarizer (<0.5 dB) the output power of the polarized SFS is predicted to approach that of a standard, unpolarized SFS, i.e., the(More)
In response to comments received from public review of the first draft proposed Fortran standard (X3J3/S8.104), a number of changes have been made and a revised draft proposed standard (X3J3/S8.112) has now been released for further public review. The following outline summarizes the technical changes that were made on the basis of the first review. A(More)
The Fortran community has, over the past several years, devoted considerable effort to development of modern, effective repetition control structuring for Fortran. Some highlights of these efforts are reviewed here. Recently the American Fortran standards committee has tentatively adopted the basic elements of an extensible looping facility. This facility(More)
