摘要： A Raman amplifier includes at least a first and a second optical Raman-active fiber disposed in series with each other. A first pump source is connected to the first Raman-active fiber, and is adapted for emitting and coupling into the first Raman-active fiber a first pump radiation including a first group of frequencies. A second pump source is connected to the second Raman-active fiber, and is adapted for emitting and coupling into the second Raman-active fiber a second pump radiation including a second group of frequencies. The whole of said first and second group of frequencies extends over a pump frequency range having a width of at least the 40% of the Raman shift. The minimum and the maximum frequency in each of said first and second group of frequencies differ with each other of at most the 70% of said Raman shift.

摘要： A tunable resonant grating filter that can reflect optical radiation at a resonant wavelength, the resonant wavelength being selectively variable. The filter includes a diffraction grating, a planar waveguide, and a light transmissive material having a selectively variable refractive index to permit tuning of the filter, the light transmissive material forming a tunable cladding layer for the waveguide, preferably a liquid crystal material. The diffraction grating is placed on the opposite side of the tunable layer with respect to the planar waveguide, thereby making it possible to tailor the grating structural parameters to the desired bandwidth of the filter response without significantly affecting the tunability of the filter. Within the resonant structure, the core layer, i.e., the waveguide, can be placed close to the tunable layer either in direct contact with the tunable layer or with an interposed relatively thin intermediate layer(s) between the core and the tunable layer.
