摘要： An amplifying optical fiber includes an inner core, an inner cladding, a depressed trench, and an outer cladding (e.g., an outer optical cladding). Typically, the inner core includes a main matrix (e.g., silica-based) doped with at least one rare earth element. The depressed trench typically has a volume integral V13 of between about −2200×10−3 μm2 and −1600×10−3 μm2.

摘要： Disclosed is a temperature and strain sensing optical fiber including a first doped radial zone (Z1) with an associated first Brillouin shift (BS1) caused by the doping of said zone (Z1) and a second doped radial zone (Z2) with associated second Brillouin shift (BS2) caused by the doping of said second zone (Z2). The concentration and/or composition of the doping materials in said first and second radial zones are chosen such that the first Brillouin Shift (BS1) is different from the second Brillouin Shift (BS2) for all variations of said Brillouin Shifts (BS1, BS2) caused by temperature and/or strain.

摘要： Disclosed is a stimulated Raman scattering effect (SRS), amplifying optical fiber that includes a central core comprising a dielectric matrix that is capable of vibrating at a given frequency (ωRaman) under the effect of a pump signal. The optical fiber includes at least one kind of metallic nanostructure that is capable of generating surface plasmon resonance (SPR) in the optical fiber. The metallic nanostructures have a shape and composition such that the frequency of their surface plasmon resonance (ωplasmon) corresponds to the frequency of the pump signal (ωpump) and/or the frequency of the optical signal transmitted in the optical fiber (ωsignal).

摘要： An optical fiber includes a central core and an optical cladding. The central core includes a core matrix surrounding nanoparticles. The nanoparticles include rare earths, a nanoparticle matrix, and an outer layer. The nanoparticle matrix surrounds the rare earths, and the outer layer surrounds the nanoparticle matrix. The atomic ratio of nanoparticle matrix atoms other than oxygen to rare earth atoms is typically between about 300 and 1,000. The outer layer, which typically has a thickness of between about 1 nanometer and 2 nanometers, includes an outer layer matrix that is substantially free from rare earths.

摘要： Disclosed is an amplifying optical fiber that includes a central core that is suitable for transmitting and amplifying an optical signal and a surrounding optical cladding that is suitable for confining the optical signal transmitted in the central core. The central core is formed from a main matrix that contains nanoparticles doped with at least one rare earth element. The weight concentration of the rare earth dopants in the nanoparticles is typically between about 1 and 20 percent, and the nanoparticle concentration in the central core's main matrix is between about 0.05 percent and 1 percent by volume. The disclosed optical fiber incorporates rare earth ions at high concentrations yet avoids the phenomenon of photodarkening at high transmission power.
