Abstract

AMPLIFICADORES PARA FIBRA OPTICA. UN CHIP AMPLIFICADOR (20) QUE TIENE UNA FACETA TRASERA (23) PROVISTA CON UN REVESTIMIENTO REFLECTIVO. LAS SEÑALES OPTICAS ENTRAN Y LAS SEÑALES AMPLIFICADAS SALEN POR MEDIO DE FIBRAS OPTICAS (21,25,30) Y EL ACOPLADOR DIRECCIONAL (24). SE REQUIERE UN ALINEAMIENTO SIMPLE DE FIBRA A AMPLIFICADOR ENTRE LA COLA DE LA FIBRA (25) Y LA FACETA FRONTAL (22), LA CUAL ESTA PROVISTA CON UN REVESTIMIENTO DE MUY BAJA REFLECTIVIDAD. EN ESTA CONFIGURACION LA AMPLIFICACION AUMENTA EN COMPARACION CON LAS CONFIGURACIONES CONVENCIONALES DE AMPLIFICACION EN LINEA.
