摘要： An optical amplifier having a tellurite glass as an optical amplification medium, characterised by comprising:

a dispersion medium which is placed on at least one position in the front of or at the back of the optical amplification medium, wherein
the dispersion medium compensates for dispersion of wavelengths by a value of chromatic dispersion that takes a plus or negative number opposite to a value of chromatic dispersion for the optical amplification medium. In the figure, an optical signal enters from the left and exits from the right of the optical amplifier. Input signal light passes through optical isolator 201a and then, combined with excitation light from excitation light source 202, through optical coupler 203. Then the combined signal light passes into optical fiber 205 for optical amplification after passing through a dispersion medium 204. Signal light amplified by optical fiber 205 is then outputted through optical isolator 201b.

摘要： A tellurite glass as a glass material of optical fiber (104) and optical waveguide has a composition of 0 2 O 3 ≤ 20 (mole %), 0 ≤ Na 2 O ≤ 35 (mole %), 0 ≤ ZnO ≤ 35 (mole %), and 55 ≤ TeO 2 ≤ 90 (mole %). The tellurite glass allows an optical amplifier and a laser device that have broadband and low-noise characteristics. In a splicing structure of non silica-based optical fiber (as a first fiber) (301) and a silica-based optical fiber (as a second fiber) (302), optical axes (301a, 302a) of the first and second optical fibers (301, 302) are held at different angles θ 1 and θ 2 (θ 1 ≠ θ 2 ) respectively from a vertical axis of a boundary surface between their spliced ends, and a relationship between the angles θ 1 and θ 2 satisfies Snell's law represented by an equation of sin θ 1 / sin θ 2 = n 2 / n 1 (where n 1 is a refractive index of the first optical fiber and n 2 is a refractive index of the second optical fiber) at the time of splicing the first and second optical fibers (301, 302).

摘要： A twin coupler system includes first and second optical couplers that couple a multimode pump fiber into a double-clad active primary fiber. The pump fiber carries multimode pump power from a multimode source. The primary fiber, on the other hand, carries optical information signals on the single mode core that are amplified through the pump power. A system and method for manufacturing the twin coupler system constructs the first coupler by preparing first portions of the primary and pump fibers for coupling and performing fusion and tapering operations on the primary and pump fibers at the first portions, and constructs the second coupler by preparing second portions of the primary and pump fibers for coupling and performing fusion and tapering operations on the primary and pump fibers at the second portions. The fusion and tapering operations at the second portions are dependent upon the fusion and tapering operations performed at the first portions so as to achieve a maximum coupling efficiency of the pump power from the pump fiber to the primary fiber for the entire twin coupler system.
