Abstract

AMPLIFICADOR DE FIBRA óTICA. Amplificador de fibra ótica incluindo uma primeira fibra ótica dopada com érbio e fósforo, para amplificação de luz de sinal excitada pelo érbio, uma segunda fibra ótica conectada a uma extremidade da primeira fibra ótica, dopada com érbio e alumínio, e apresentando um declive de espectro de ganho oposto a primeira fibra ótica de acordo com a inversão de população do érbio, para amplificação da luz de sinal liberada pela primeira fibra ótica, uma fonte de bombeamento laser conectada à outra extremidade da primeira fibra ótica, para excitação do érbio da primeira e segunda fibras óticas, e um acoplador de luz para acoplamento da luz de bombeamento a partir da fonte de bombeamento laser para a luz de sinal e liberando a luz resultante para a primeira fibra ótica. Dois tipos de EDFs apresentando diferentes espectros de ganho são usados, de modo que o espectro de ganho de cada um dos EDFs varie ativamente com a potência de entrada da luz de sinal ou potência de entrada de luz de bombeamento. Assim, é mantido um ganho inteiramente achatado.
