All-optical fiber-based amplitude jitter magnifier

Experimental demonstration of an ultrafast all‐optical bit‐error indicating scheme

“…As a consequence, only one judge threshold is necessary to analyze the EBIS and to identify the potential errors. Less importantly, one can also notice from the various experiments that, in the EBIS, ''1'' bits are affected by a much higher jitter than the ''0'' bits, which is consistent with the regime of amplitude jitter magnification [10]. Moreover, the previously mentioned double peaked structure can be guessed.…”

“…Indeed, the architecture described in Figure 1 is well-known in the context of optical regeneration [6][7][8][9], in which the aim is not to facilitate the detection of errors but to limit output pulse train jitter and act as an all-optical power limiter: this requires a TF with a large plateau characterized by an inflexion point. Another application based on similar architecture has also been recently proposed and targets the all-optical magnification of amplitude jitter [10]. Our purpose is here very different from optical regeneration or optical magnification so that the requirements on the TF differ significantly.…”
