São desenvolvidos amplificadores de fibra dopada com érbio de núcleo coaxial (EDFAs) com propriedade de espectro de ganho autorregulado. A operação de um EDFA de núcleo coaxial é baseada na separação parcial dos caminhos de luz para diferentes canais de comprimento de onda nos guias de onda acoplados direcionalmente de uma geometria de núcleo coaxial. O grau de equalização do canal depende dos parâmetros geométricos e ópticos do EDFA de núcleo coaxial e dos níveis relativos de potência do canal. Uma análise numérica baseada na teoria do modo acoplado e na equação de taxa mostra que, sob condições totalmente otimizadas, um EDFA de núcleo coaxial fornece taxas de equalização superiores a -0.4 dB por dB de desequilíbrio de potência de entrada no caso com dois WDM canais. Um experimento em cascata demonstra o efeito dos EDFAs de núcleo coaxial na equalização de potência do canal em links de fibra com um pequeno número de canais WDM.

Abstract: Coaxial-core erbium-doped fiber amplifiers (EDFA's) having a property of self-regulated gain spectrum are developed. The operation of a coaxial-core EDFA is based on the partial separation of the light paths for different wavelength channels in the directionally-coupled waveguides of a coaxial-core geometry. The degree of channel equalization depends on the geometrical and optical parameters of the coaxial-core EDFA and on relative channel power levels. A numerical analysis based on the coupled-mode theory and on the rate equation shows that, under fully optimized conditions, a coaxial-core EDFA provides equalization rates in excess of -0.4 dB per dB of input-power imbalance in the case with two WDM channels. A cascade experiment demonstrates the effect of coaxial-core EDFA's toward channel-power equalization in fiber links with a small number of WDM channels.
