Abstract
An optical amplifier includes an optical fiber having a core doped with transition metal ions, and at least one glass cladding enclosing the core. By using the fiber, the optical amplifier of the invention has a gain bandwidth of more than 300 nm including 1300-1600 nm band in low-loss optical communication.
Claims13
An optical amplifier comprising:
- an optical fiber comprising:
- a single crystalline core doped with transition metal ions, and an inner cladding and an outer cladding enclosing the core wherein the single crystal core is made from a material selected from a group consisting of Y3AL5O12 and garnets and the inner cladding is made by a material selected from the group consisting of Y3AL5O12 and silica.
