Feasibility study of SOA-based noise suppression for spectral amplitude coded OCDMA
Feasibility study of SOA-based noise suppression for spectral amplitude coded OCDMA
We investigate the benefits of employing a saturated SOA to reduce optical noise in an incoherent light OCDMA system. In the context of spectrum-slicing, SOA-based noise suppression has shown significant potential for enhancing the signal quality of noisy light. In this paper, we evaluate the viability of the technique for spectral amplitude coded OCDMA, and show that the benefits of SOA-based noise suppression do not extend readily to this application, due to post-SOA optical filtering effects at the receiver. However, appreciable performance improvements can in principle be realized through optimized system and decoder design.

Abstract
We investigate the benefits of employing a saturated SOA to reduce optical noise in an incoherent light OCDMA system. In the context of spectrum-slicing, SOA-based noise suppression has shown significant potential for enhancing the signal quality of noisy light. In this paper, we evaluate the viability of the technique for spectral amplitude coded OCDMA, and show that the benefits of SOA-based noise suppression do not extend readily to this application, due to post-SOA optical filtering effects at the receiver. However, appreciable performance improvements can in principle be realized through optimized system and decoder design.
