摘要： A looped WDM optical network comprises an optical loop with optical amplifiers (12,16) between the sections of the loop (11) and with ASE recirculation in the loop. At a point of the loop a laser beam is injected and allowed to circulate in the loop with the laser beam being centered around a λ LINK wavelength where it is desired that a lasing peak be generated. This supplies high network strength in terms of section loss variations and greatly improves the OSNR of the WDM signal. High network survivability is also achievable.

摘要： An RF signal generator (50) has an optical part (10) for outputting optical carrier signals separated in optical frequency, and a modulator (20) arranged to modulate the optical carrier signals with an intermediate frequency to generate sidebands. A phase modulation is applied to one or more of the sidebands or the optical carriers, without applying the phase modulation to others of the signals, and the modulator has integrated optical paths for both the phase modulated signals and for the others of the signals. A detector part (30) carries out heterodyne detection to combine the phase modulated and other signals to output an RF signal having the phase modulation. By having integrated optical paths, the relative phase of these optical paths can be more stable than using a fiber sagnac interferometer and optical isolator thus enabling use in advanced radio communications.

摘要： A method of extracting a predetermined channel from an OTDM signal includes the steps of combining at the inlet of an SOA the OTDM signal and an impulsive signal with impulses temporally synchronized with the channel to be extracted to produce in the SOA FWM, XGM and XPM effects which shift to a length c the channel chosen for extraction with c outside the length d of the OTDM signal with the other channels outlet from the SOA and filtering the SOA outlet to extract components with c d that represent respectively the desired channel and the cleaned OTDM signal. A multiplexer in accordance with the method includes an inlet (14) of an OTDM signal sent to an SOA (24) together with an appropriate impulsive signal. The SOA outlet is filtered by filters (28, 29) to obtain the signal of the extracted channel (16) and the cleaned OTDM signal (15).

摘要： A method and an apparatus for carrying out a chemical-physical analysis, such as a spectroscopic analysis, an absorption analysis, a scattering analysis, etc. on one or more regions of a sample (11 ), provides prearranging a source (1 ) of a first electromagnetic radiation comprising a plurality of components with respective wavelength, prearranging a plurality of sites (9) distributed on a determined surface to emit the first radiation, arranging such surface facing a corresponding region of a sample (11 ) such that the whole surface thereof is attained by the first radiation, emitting the first radiation on the sample (11) thus causing the emission of a second radiation by the sample (11 ), which is analysed to associate an intensity of the second radiation to each region and wavelength. For each of the wavelength of the first radiation, a wavelength code is selected by which respective components of the first radiation are coded; the coded components are joined together to form the first electromagnetic radiation which is distributed in a plurality of radiation beams. Such beams are conveyed to respective emission sites (9), for each of which an emission site (9) code is selected, a radiation beam being codified by said code. A decoding of the of the second radiation produces a plurality of fractions, each fraction associated to a wavelength of the first radiation such that for each emission site (9) it is possible to instantaneously compare each fraction associated to a respective wavelength with a component of the first radiation having the same wavelength, the components of the first electromagnetic radiation being emitted simultaneously. The steps of wavelength coding and of site coding, and possibly also other coding steps may be earned out subsequently with respect to one another, or at the same time. The method and the apparatus allow reducing the time required to carry out said analysis.
