Optical fibers are by far the most attractive elements with which to create optical systems in the medical or biological applications of light. They are usually made up of long, thin glass rods that turn out to be very easy to handle. Moreover, their thinness and flexibility allow reaching inaccessible regions in the body without pain and discomfort to

Analysis of the geometry of recursive tilings has led to the development of a new class of highly ordered optical composites that exhibit fractal surface character. These objects are, we believe, the first engineered fractal objects. The mathematics of tiling and examples of fractal fiber array devices are reviewed.

Unlabelled - This study aimed to evaluate the potential therapeutic effects of leaves and fruits from Algeria. The total phenolic and flavonoid contents, sun protection factor, antimicrobial, antifungal, and antioxidant activities such as DPPH, ABTS, FRAP, CUPRAC, and o-phenanthroline reduction were determined.

The Fourier transform of a coherent optical image can be evaluated physically by use of a single lens plus free-space propagation, thereby providing the basis for the field of Fourier optics. I point out that one can similarly evaluate the discrete Fourier transform of a sampled or pixelated optical array physically by passing the discrete array ...

In the preceding chapter it was shown that, under ideal conditions, a light wave in a dielectric material would form an envelope soliton. However, in a real three-dimensional fiber, the light wave propagates with finite loss. In this chapter, we discuss the practical conditions needed for an optical pulse to become a soliton in a dielectric waveguide.

In the near future nonlinear optics should probably revolutionize the world of telecommunications and computer technologies. With lasers producing highintensity and short-duration optical pulses, it is now possible to probe the interesting, and potentially useful, nonlinear effects in optical systems and waveguides.
