Abstract

Patente de Invenção para <B>"AMPLIFICADORES OPTICOS DE SINTONIZAçãO DE COMPRIMENTO DE ONDA DE BOMBA, E USO DOS MESMOS EM SISTEMAS MULTIPLEXADOS DE DIVISãO DE COMPRIMENTO DE ONDA"<D>. As variáveis e parâmetros previamente compreendidos para afetar o espectro de ganho de um amplificador óptico 13 foram: (1) os comprimentos de onda a serem amplificados; (2) os níveis de energia de entrada naqueles comprimentos de ondas; (3) as caracteristicas do meio de amplificação 20; (4) o espectro de perda de inserção dos componentes do amplificador, incluindo qualquer filtro (s) usados para planarização de ganho; (5) a faixa de banda escolhida para bombear o meio de amplificação 20; e (6) a quantidade total de energia de bomba suprida na escolha da faixa de bomba. Uma variável fundamental adicional foi identificada, que pode ser usada para controlar o espectro de ganho de um amplificador óptico 13, a saber, o comprimento de onda central do espectro da energia de saida de bomba dentro da faixa de bomba escolhida. Processos e aparelhos para uso desta variável para esta proposta são revelados. Por exemplo, um sistema de transmissão é revelado, tendo um transmissor 11 e um receptor 10, conectados por uma fibra óptica 12. Uma pluralidade de amplificadores ópticos 13 estão localizados ao longo da fibra óptica 12, para amplificar canais de sinais entre o transmissor e o receptor. Cada um dos amplificadores apresentam uma fonte de luz de bomba 21, o comprimento de onda do qual é tal que contribuições ao ganho diferencial devido ao comprimento de onda de luz de bomba relativos aos efeitos, é substancialmente reduzido. Também revelado é um sistema de transmissão WDM, tendo uma trajetória de transmissão, incluindo uma concatenação de amplificadores ópricos bombeados de diodo de laser 13, no qual o espectro de ganho de um amplificador é controlado pelo menos em parte por um volteamento de retorno, que regula a temperatura de sua bomba de diodo de laser 21. O volteamento de retorno pode, por exemplo, derivar seu sinal de controle de uma medida da corrente de acionamento aplicada à bomba, do comprimento de onda de emissão da bomba, ou da disparidade entre a saida de energia a partir do amplificador em um dos canais de sinais multiplexados, e que formam pelo menos um outro dos canais.
