Intensity modulation of light transmitted in curved optical fibres

More light in Polish optical fibres

Optical communications infrastructure is undergoing an intense development in his country now. A number of international investors and domestic operators are building from the beginning, modernizing or developing proprietary network or leasing wide area systems on a large scale. The aggregate level of these processes is of the order of bil. $. Despite of this the network is not homogeneous, has...

Slow and fast light in optical fibres

The development of high-quality silica optical fibres with excellent transmission capabilities has directly contributed to the tremendous expansion of the global communication network. The success is due to their unrivalled low-loss performance (typically 50% of light is still present after a 15-km transmission distance), their wide bandwidth, which allows terabits per second of information to ...

] 1 6 Se p 20 02 Computational studies of light acceptance and propagation in straight and curved optical fibres

A Monte Carlo simulation has been performed to track light rays in cylindrical fibres by ray optics. The trapping efficiencies for skew and meridional rays in active fibres and distributions of characteristic quantities for all trapped light rays have been calculated. The simulation provides new results for curved fibres, where the analytical expressions are too complex to be solved. The light ...

Three-dimensional mapping of the light intensity transmitted through nanoapertures.

A general method to map the 3D spatial distribution of light emerging from nanoscale apertures is presented that uses photolithographic techniques to create polymer replicas of the intensity distribution. The resulting features varied with aperture diameter and exposure time and showed good correlation with theory. This method provides direct visualization of the intensity distribution in close...
