Paper Abstract

High isolation 1480-1550 nm WDM using fused fibers has been achieved. Several techniques have been tested but 2 by 2 fused couplers cascaded with filters give best results. Indeed, they demonstrate an isolation greater than 30 dB over 25 nm for the 1480-1550 nm WDM with a maximum insertion loss of 0.3 dB. Furthermore, the polarization dependence has been reduced to 0.1 dB. This device can therefore realize very efficient demultiplexing in EDFAs at low price.
