Abstract
This paper aims to study the performance of spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems based on single photo-diode (SPD) detection under various types of optical filters decoder schemes (Optical Gaussian filter, Thin film and Fiber Bragg Grating (FBG)). In our work, we utilized Modified Double weight (MDW) code as one of the SAC codes; the proposed system is performed by using single photodiode for each user. The results characterizing the bit-error-rate (BER) of 10−12 with respect to the data rate show that the SDP offers a significant improved performance for long haul applications (wide area network (WAN)) over other types of SAC-OCDMA detection techniques. Furthermore, the FBG filters have higher dispersion than Gaussian and thin film filters. The comparison states that the optical Gaussian filters have better filter amplitude response leading to lower dispersion bandwidth reduction, while FBG filters have higher dispersion which could reduce the goal of 622 Mbps channels in SPD detection scheme.
