In this paper, we have demonstrated the excellent performance of an externally injected gain-switched laser source followed by a NC FBG (nonlinear group delay and nonlinear reflection profile) by employing it in an 80 Gb/s OTDM system. A major improvement in system sensitivity (3.5 dB) achieved by the increased suppression of the temporal pedestals was recorded when compared with a gain-switched source employing a linearly chirped grating.
