Analysis of gain improvements through a pump reflector in Er3+-doped optical amplifiers in the presence of concentration quenching
Analysis of gain improvements through a pump reflector in Er3+-doped optical amplifiers in the presence of concentration quenching
We numerically examine the small-signal gain improvements possible when the pump light is reflected in erbium-doped amplifiers suffering from concentration quenching caused by homogeneous and inhomogeneous energy-transfer upconversion. For an unquenched amplifier, the improvement is larger for a pump power of 20 mW than it is at 100 mW. On the other hand, at a pump power of 100 mW, the reflector is found to be efficient for a quenched amplifier, with a maximum improvement of 6.5 dB. We also find that the reflector is more efficient at 1.535 μm than it Is at 1.550 μm, under all examined operating conditions.

Abstract
We numerically examine the small-signal gain improvements possible when the pump light is reflected in erbium-doped amplifiers suffering from concentration quenching caused by homogeneous and inhomogeneous energy-transfer upconversion. For an unquenched amplifier, the improvement is larger for a pump power of 20 mW than it is at 100 mW. On the other hand, at a pump power of 100 mW, the reflector is found to be efficient for a quenched amplifier, with a maximum improvement of 6.5 dB. We also find that the reflector is more efficient at 1.535 μm than it Is at 1.550 μm, under all examined operating conditions.
