Paper Abstract

The influence of the center wavelength of fused-taper WDM couplers for use in EDFAs with pumping around 1480 nm is investigated. This is done by computer simulations of the EDFA using measured coupler characteristics of three manufactured WDM couplers. It is shown that using a WDM coupler with a broadened channel spacing a higher bandwidth of the gain and the noise figure spectrum is obtained due to lower excess and insertion losses. In addition, the manufacturing process of these WDM couplers is highly reliable.
