Abstract
We present a simple scheme for implementation of optical single sideband suppressed carrier (OSSB-SC) modulation based on the use of standard MZM and passive fiber optic components. The function of the proposed modulator is also theoretically predicted. A Sagnac interferometer structure is used for sideband suppression. The light propagating in one direction is orthogonally linearly polarized to the oppositely propagating light. The orthogonal polarization is implemented by a non-reciprocal optical element. The optical carrier is attenuated by appropriately setting the Mach-Zender Modulator (MZM) at quadrature bias point. We will experimentally demonstrate sideband suppression and carrier attenuation up to 28 dB by using all commercially available components.
