Dispersion supported transmission (DST) is a new technique which combines intensity modulation (IM) and optical frequency modulation (OFM) to allow transmission spans beyond the usual dispersion limit. Using computer simulation, DST limitations are evaluat ...

We demonstrate a method to achieve an extremely wide and flexible external control of the group velocity of signals as they propagate along an optical fiber. This control is achieved by means of the gain and loss mechanisms of stimulated Brillouin scatteri ...
Polarization dispersion is an effect which may cause data rate penalty in optical links. This is caused by the combined effect of fibre birefringence and polarization couplings due to environmental perturbations. Polarization dispersion is therefore a stoc ...
Structured filamentous zeolitic materials were prepd. by depositing ZSM-5 coatings on glass fiber supports. A homogeneous coverage of the support filaments was obtained by prepg. MFI crystals in F-contg. media at neutral pH. The samples were characterized ...
We demonstrate the possibility of broadening the emissions spectra of superfluorescent fiber lasers by combinations of different kinds of single-mode doped silica fibers. We obtained an optical bandwidth of more than 70 nm (FWHM) between 1030 and 1100 nm u ...
A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM), the number of alarms and the difficul ...
Summary form only given. All-fiber phase modulators have recently received considerable attention because of their advantages for applications in the field of lightwave technology. In this paper, new results are presented on the characterization of all-fib ...
The feasibility of a survivable all-optical transport network over standard single-mode fibre between eight major European cities is investigated. The chosen topology is intended to ensure survivability after a link or a node failure. The maximum transmiss ...
Birefringent single-mode fibers with random polarization mode coupling and polarization dependent losses are considered. The effect of these losses on polarization mode dispersion (PMD) is computed. The relevant number is found to be the differential loss ...
