In this paper, we initially show the design of the pulse source based on the EI GSLD employing a NC FBG. The design of the NC FBG is based on an initial complete characterization of the gain-switched pulse using a technique known as Frequency Resolved Optical Gating (FROG). We subsequently use the measured nonlinear chirp across the pulse to design and fabricate an NC FBG. This process involves the initial creation of the group delay response for the FBG based on the group delay data derived from the FROG measurements of the externally injected gain-switched pulse. The FBG target group delay response is simply selected as the inverse to the pulse group delay response, which should result in the pulse having a constant group delay profile overthe pulse bandwidth after it has been reflected from the FBG.
