摘要： The present invention relates to a new model for interpreting interferometric measurements, able to lead to a new method, system (10) and device (27) for measuring the PMD (Polarisation Mode Dispersion) of an optical fibre (11). The model, which is based on the theory of propagation of the optical signal as can be determined according to the socalled Prindpal States of Polarisation (PSPs) of the fibre, leads to a new interpretation of the interferogram generated with the interferometric measurements and is characterized in that it identifies in said interferogram a central peak and two side lobes. Thanks to this new model, it is possible to determine the PMD of the fibre based on the information content associated to at least one of the two side lobes identified in the interferogram.

摘要： A multi-stage optical amplifier for a fiber-optic transmission system, in particular, an amplifier having a multi-stage configuration that allows an optimization of its performance with respect to noise, gain and bandwidth. The multi-stage amplifier has a first amplifying stage including a rare-earth doped optical active fiber; a second amplifying stage connected to the first amplifying stage, the second amplifying stage including a tellurite-based active fiber doped with a rare earth element; and a third amplifying stage connected with the second amplifying stage, the third amplifying stage including a silica-based fiber.

摘要： These improvements to semiconductor lasers allow the fabrication of high-efficiency photoemitting devices thanks to a decrease in the threshold current necessary to optical emission stimulation. They consist in the application of a suitable magnetic field apt to confine carrier current within a limited zone of the active layer.
