• Abstract : Coherent optical code division multiplexing is a novel method using the phase of optical pulse as the bipolar code for future fiber-optic communication networks. Some optical bipolar codes with a repetition frequency over 10 GHz are generated experimentally and their fundamental propeties are elucidated. The key features of the method, auto- and cross-correlation of these codes, are shown experimentally and compared with the theoretical results. Interference between two optical narrow pulses with high repetition frequency is investigated experimentally under various conditions of optical phase and wavelength as the basis of the method. A guaranty of realization of the technique is shown.
