Paper Abstract

A novel scheme to realize optical single-sideband modulation using only one electroabsorption modulator is presented. The scheme is based on the cancellation between the nonlinear phase due to dispersion and the linear phase due to optical delay in a Sagnac loop. Our theoretical analysis and experiment results show that optical single-sideband modulation can be realized in a very simple configuration. The scheme is independent of optical wavelength; it also avoids the problem of coherent interference, resulting in stable generation of optical single-sideband signals.
