Abstract

The sensitivity performance of an optically preamplified PPM receiver is evaluated, including the effect of timing jitter, through the use of an improved Gaussian approximation. A potential sensitivity of 23.6 photons/bit is demonstrated in the unjittered case, for the parameters considered, with the jittered optimum being at worst only 1 dB less sensitive. These results both surpass the fundamental sensitivity limit of an on-off keyed non-return to zero (OOK NRZ) system. The results predict that wrong slot and jitter errors first become dominant at a PPM coding level higher than that suggested by an earlier model.
