摘要： Disclosed is a Raman laser device (10) having a first cavity in which lasing occurs at a first frequency, and at least one second cavity in which lasing occurs at a second frequency. Thereby respective first and second waves inside the respective cavities are generated having a first power and a second power, respectively. Further, beams propagating outside the cavities are generated by coupling out a part of the first power and a part of the second power utilizing respective output mirrors. The part of the second power that is coupled out is attenuated without attenuating the complementary part of the second power remaining in the second cavity. The Raman laser device is characterized in that the part of the second power that is coupled out is attenuated utilizing at least one Fiber Bragg Grating (46, 62).

摘要： The gain characteristic of a distributed Raman amplifier (RA) is controlled by estimating its gain curve in a simulation, selecting NP data channels (λ1, λ2, λ3) for an online measurement and determining target gain values for the selected channels from the simulated gain curve (24). The number of selected channels corresponds to the number of pump wavelengths (λP1, λP2, λP3). A controller (CTR) varies the power of at least one of the pump light signals (λ1, λ2, λ3) to minimize a power difference between the measured power value of any of the NP signal channels and its estimated target gain value.

摘要： A Raman-amplified optical transmission system (1) comprises at least one transmission fiber (4) for Raman amplifying of an optical signal (S), at least one corresponding pump (5, 5.1, 5.2, 5.3) for pumping the transmission fiber (4) at a plurality of pumping wavelengths (λP1, λP2, λP3), at least one Lumped Raman Amplifier LRA (9, 10, 11) for imparting an additional gain on the optical signal (S), and at least one corresponding LRA pump (10, 10.1) for pumping the lumped Raman amplifier LRA. According to the present invention the LRA pump (10, 10.1) is adapted to operate at a single LRA pumping wavelength (λP3), which is essentially equal to one of the pumping wavelengths (λP3) of the pump (5, 5.3) for pumping the transmission fiber (4). In this way the present invention provides an optical transmission system (1) and a corresponding method for amplifying optical signals (S), respectively, which distinguish themselves with respect to cost effectiveness, compactness of realisation, and possible gain control, particularly in relation with constant-gain operation, from prior art solutions.

摘要： A Raman amplifier (10) including at least one amplifying fiber (12) and a coupler (14) for coupling at least first (16) and second (18) pump laser modules to the amplifying fiber (12), the first pump laser module (16) including a frequency discriminator (24) for selecting an optical frequency to be emitted with an optical power exceeding an optical power of remaining optical frequencies that are also emitted by the first pump laser module (16). The first optical frequency is spaced apart from a local maximum (28; 36; 48) in optical power of the remaining optical frequencies, and the second pump laser module (18) emits at an optical frequency one Stokes-frequency above the frequency of the local maximum (28; 36; 48). The first optical frequency and the frequency of the local maximum are chosen on Stokes-frequency above the signal frequency range. As a consequence, the Raman gain provided in the Raman amplifying fiber 12 is broadened.

摘要： The invention is dealing with a Raman amplifying device comprising an optical path, pump sources for generating a plurality of Raman pump signals and means for coupling the plurality of Raman pump signals into the optical path for backward pumping. The plurality of optical Raman pump signals are time-division multiplexed by multiplexing controlling means and the controlling means apply a modulation frequency beyond the corner frequency of the co-propagating modulation transfer function. The method to modulate the time division multiplexed Raman signal gives a condition to avoid the increase of double Rayleigh scattering noise.
