Abstract

Dispersion has very strong detrimental effects on high data rate incoherent transmission systems. Situation gets much worse when data bits become only a few picoseconds long. In this paper we investigate how the dispersion can affect an optical auto-correlation function in optical code division multiple access (OCDMA) systems when data are carried by two-dimensional wavelength-hopping time-spreading codes based on multi-wavelength picosecond pulses. We show how chromatic dispersion and changes of optical fiber temperature can distort the OCDMA auto-correlation. We also demonstrate a simple method for efficient mitigation of these effects.
