Generation of four-wave mixing products inside WDM C-band 1W Er3+/Yb3+ amplifier
03 February 2000
The generation of four-wave mixing (FWM) products inside a +30dBm output power booster Er3+/Yb3+ amplifier is reported. The corresponding nonlinear Kerr parameter gamma was derived by measurement of the FWM efficiency between two co-propagating signal pumps. Experimental and theoretical FWM transmission impairments have been confirmed for a 2.5Gbit/s eight-channel WDM transmission system.
