Coherence coding of optical pulses for code-division multiple access

Abstract

The technique of precise path matching to produce coherent summation of optical pulses at the output of an optical delay network offers great scope for optical code-division multiple-access (CDMA) networks. Balanced detection can be used to reject incoherent signals before thresholding,1·2 whereas purely incoherent techniques must rely on time spreading to distinguish wanted from unwanted users.
