摘要： Aspects of an optical communications network are described that include two or more optical fibers arranged to allow communication in the same or in opposite directions. The optical network includes a first optical amplifier coupled to the first optical fiber, a second optical amplifier coupled to the second optical fiber, and an optical coupler that allows excess optical power from the first optical fiber to be provided for amplification of signals traversing the second optical fiber. The disclosed systems and devices thus enable excess power from one channel to be utilized to enable amplification of signals traveling on a different channel.

摘要： A dual wavelength pumping system and method have been developed to improve the efficiency of laser systems operating in the raid infrared region has been developed, in a conventional system the ions are excited from a ground state to an upper lasing state using a light pump. They then undergo a laser transition to leave the ion in a long lived post lasing excited state from which it eventually decays back to the ground state. In contrast they present system uses a first light pump to pump ions from the ground state to the post lasing state, and a second light pump to pump ions from the post lasing state to the upper lasing state. This system thus exploits the long lifetime of the post lasing state to enable it to become a virtual ground state for the second laser allowing continued cycling of ions between the upper lasing state and the post lasing state. A system using an Erbium, doped fiber generated a 3.5 μm laser output with an average power of over 250 mW and an initial slope, efficiency of 25.4% (previous system have only generates less than 10 mW of power with efficiencies of 3%).

摘要： A clad mode stripper is provided on a passive double-clad fiber guiding amplified light signal downstream from a gain block. The fiber is configured with an upstream end stripped from a protective coating. A light absorbing mixture is applied to the exposed cladding of the fiber receiving unwanted pump light. The mixture includes a host material and a plurality of diffusers which are operative to scatter cladding light incident thereon and embedded in the host material so as to define upstream and downstream decoupling zones. The diffusers are selected from either silicone polymers with a refractive index lower than that of the host material or from metal particles and lower the effective refractive index of the mixture so that it at most equal to that of the cladding. The mixture is operative to gradually remove substantially entire unwanted light guided by the cladding so that the downstream decoupling zone is heated at a temperature lower than that of the upstream zone.

摘要： Embodiments of optical fiber may include cladding features that include a material (e.g., fluorine-doped silica glass) that may produce a very low relative refractive index difference with respect to cladding material in which the cladding features are disposed. This relative refractive index difference may be characterized by (n1−n2)/n1, where n1 is the index of refraction of the cladding material in which the cladding features are included, and n2 is the index of refraction of the cladding features. In certain embodiments, the relative refractive index difference may be less than about 4.5×10−3. In various embodiments, the configuration of the cladding features including, for example, the size and spacing of the cladding features, can be selected to provide for confinement of the fundamental mode yet leakage for the second mode and higher modes, which may provide mode filtering, single mode propagation, and/or low bend loss.
