A Novel Joint-Matching Method for Optimizing the Compatibility between Optical Source and En/Decoder of OCDMA
Optical en/decoder is one of the key components in Optical Code Division Multiple Access (OCDMA) systems. Therefore, the improvement of performance of en/decoder is very necessary for improving the whole performance of OCDMA system. Among all kinds of factors which affecting the performance of en/decoder, the compatibility between optical source and en/decoder is proved to be an inevitable item. In this paper, as to equivalent phase shift superstructured FBG (EPS-SSFBG), an advanced en/decoding technology, both optimum pulse width and proper central wavelength deviation between optical source and EPS-SSFBG based en/decoder are first investigated, which lead to a novel method of optimizing the compatibility between optical source and en/decoder. The simulation results show that there exists an optimum pulse width, not the narrowest one, fit for EPS-SSFBG based en/decoder, what’s more, it is proved advisable that proper central wavelength deviation would be beneficial when pulse width is relatively wide. Simulation and experimental results prove the feasibility and effectivity of the proposed method.
