In this letter, we investigate the effect of the turn-on time jitter in semiconductor lasers biased below threshold on the system performance. It is shown that by appropriate scrambling or coding, the pattern dependent turn-on time jitter can be reduced, which will lead to improved system performance. It is shown that the Manchester code is less sensitive to the setting of the bias point than the data with unconstrained run length, leading to a more robust link.
