Abstract: Disclosed is a fiber amplifier system including a gain fiber having a single-mode core containing dopant ions capable of producing stimulated emission of light at wavelength λs when pumped with light of wavelength λp. Absorbing ion filtering means is operatively associated with the gain fiber to alter the gain curve. If the absorbing ions are the same as the gain ions of the gain fiber, the system further includes means for preventing pump light from exciting the gain ions of the filtering means. The excitation prevention means may take the form of means for attenuating pump light. If the absorbing ions are different from the dopant ions of the gain fiber, such absorbing ions can be subjected to light at wavelength αp, but they will remain unexcited. Such absorbing ions can be used to co-dope the gain fiber, or they can be incorporated into the core of a fiber that is in series with the gain fiber.

Abstract: A method of operating an optical amplifier for improved gain and pump-to-signal conversion efficiency in a long wavelength spectral region (L-band) of the emission spectrum of a rare earth doped gain medium having a known pump absorption band involves the steps of providing an optical signal to the amplifier having a large-signal input power; and providing pumping light to the amplifier having a wavelength that is different from a center wavelength of the known pump absorption band for amplifying the optical signal. Signal gain and improved pump-to-signal conversion efficiency was demonstrated for an erbium L-band signal by detuning the pump between about ±0-30 nm on either side of the pump band center wavelength of 979-980 nm. An optical amplifier employing the described method is also disclosed.

Abstract: The amount of light coupled to an optical fiber from a laser diode is limited to a predetermined maximum power. A lens receiving the laser output is adjusted to maximize the power received at the core portion of the fiber endface. The power coupled to the fiber is then reduced to the predetermined power level by insertion of a polarizing or absorbing filter in the optical path. When a polarizing filter is employed, it is rotated until the predetermined power is coupled to the fiber. If a quarter wave plate is included, negative effects due to back reflections from the fiber end face into the laser diode can be eliminated.

Abstract: An optical amplifier includes an optical feedback resonant laser cavity (OFRC) including a power dependent loss element (PDLE) having the characteristic that as the incident laser power on the PDLE increases the cavity loss decreases. The OFRC with the PDLE provides optical gain control or optical power control for a WDM amplifier or a single channel power equalization amplifier (PEA), respectively. A 1×N×N WADM node incorporating more than one of these amplifiers, at least some of which commonly share a pump source, and a method for controlling a transient power change in a single channel optical amplifier or reducing a DC gain error in a WDM optical amplifier that are subject to dynamically variable operating conditions at an input of the amplifier, are also disclosed.
