title = "Performance improvement in an OCDMA system via two-photon absorption",
abstract = "In this paper, a simulation model and results are presented for a four user OCDMA system operating at an overall data rate of 4 Gb/s (4 x 1 Gb/s). It is shown that the nonlinear process of two-photon absorption in a semiconductor laser diode can be used to suppress multiple access interference generated by other users in the system, hence improving performance. The results presented here show that using such a device can increase the extinction ratio by 7.5 dB in comparison to a standard linear detector. These results are in good agreement with experimental findings already published.",
