PHASE CHIP FREQUENCY-BINS OPTICAL CODE DIVISION MULTIPLE ACCESS

Apparatus and system for transmitting and receiving Optical code division multiple access data over an optical Network. The apparatus comprises a spectral phase decoder for Decoding the encoded optical signal to produce a decoded Signal, a time gate for temporally extracting a user signal From the decoded signal, and a demodulator that is operable to Extract user data from the user signal. The system preferably Comprises a source for generating a sequence of optical Pulses, each optical pulse comprising a plurality of spectral Lines uniformly spaced in frequency so as to define a Frequency bin, a data modulator associated with a subscriber And operable to modulate the sequence of pulses using Subscriber data to produce a modulated data signals and a Hadamard encoder associated with the data modulator and Operable to spectrally encode the modulated data signal to Produce an encoded data signal.
