Abstract

SOA blanking is a pre-requisite in order to eliminate the transmission of spurious modes generated while switching a semiconductor tunable laser transmitter in a DWDM network. However, leakage currents associated with the large current swing applied to the integrated SOA can cause mode hops. We demonstrate that pre-emphasis of the switching signals applied to a commercially available DS-DBR laser is required to avoid cross channel interference and subsequent bit errors in a coherent DWDM network. © 2012 IEEE.
