| The need for bandwidth at the access level has driven the development of many new multiple access schemes. This paper explores a spectral encoding scheme for Optical CDMA, in which bipolar communication is accomplished by an optical chip based on planar waveguide technology. A computer model of the planar waveguide encoder/decoder is developed and used to characterize the proposed optical chip. The model is then refined by the integration of data taken from an 8 channel AWG. The simulations indicate that bit error rates (BER) of 10-9 are possible for systems as large as 32 channels. |
