| 英文摘要 | An optical fiber amplifier has an amplification stage that uses an optical fiber pumped with pump energy of a first wavelength that oscillates through the gain medium. In one embodiment, the pumping is essentially a cavity resonator that is coupled to either end of the optical fiber such that oscillating pump energy is directed into one end of the fiber and out the other, as it reflects back and forth between the ends of the cavity. Highly reflective gratings are used to maintain the oscillation of the pump energy, and a pump energy source, such as pumped doped optical fiber, is coupled to at least one of the gratings. In another embodiment, the pump source comprises multiple reflectors that are employed at each end of the fiber, and independent pump sources each having a slightly different wavelength within the absorption spectrum of the amplifier are coupled together, such that two pump wavelengths are simultaneously oscillated through the gain medium. In another embodiment of the invention, the reflective gratings are integrated directly into a portion of the pathway through which the signal to be amplified passes. This embodiment uses a pump source that causes amplification of the pump energy in the gain medium which, in turn, provides amplification of the optical signal. A two-pass embodiment is also shown in which the optical signal enters and exits from the same optical side of the amplifier fiber. An optical circulator may be used to provide the necessary unidirectional porting of the input and output signals. |
