In this type of optical amplifier, the core of a silica fiber is doped with Er3+ ions. Here, the effects of temperature on the gain parameters for short-length erbiumdoped fiber amplifiers are simulated. Temperatures were selected over a wide range (-200 to +80 degrees C) for different ion densities to simulate extreme conditions, such as the presence of liquid nitrogen. The maximum gain occurs at temperatures close to 0 degrees C, and the Er3+ concentration also plays an important role.eninfo:eu-repo/semantics/closedAccessFiber AmplifierTemperatureIon DensityGainErbiumArticle10.1007/s10812-021-01148-w8811141162-s2.0-85103225389Q4WOS:000632319000016Q4
