Abstract

In this paper we show the application of optical CDMA based on spectral encoding with integrated optical devices and discuss the use of cyclic shifted m-sequences to realize full orthogonal transmission. Degradations of the system performance due to non-ideal source spectra, crosstalk and losses in the optical coder devices are examined. Some bounds for different kinds of realization are shown. Possible sources are broadband semiconductor diodes like SLD, optical semiconductor amplifiers or multiwavelength lasers. For optical coding solutions with acoustical tunable optical filters, arrayed waveguide structures and fiber grating filters are investigated. The total network capacity will be analyzed under the above mentioned conditions and it is shown that such a network can accommodate some hundred users with a network throughput of some Gb/s.
