Abstract

We propose an optical single sideband (OSSB) modulation scheme using stimulated Brillouin scattering (SBS) in fiber to achieve OSSB modulation. Drive with 10.87‐GHz radio frequency signal into Mach–Zehnder modulator (MZM). Because of the SBS effect, lower sideband of modulated signal is amplified and upper sideband is attenuated as well. By properly adjust the phase shifter for phase difference between the two paths of electrical signal. Output signal is OSSB format, after 25‐km SMF transmission, we can observe good system performances including sideband power ratio and phase noise using by an optical spectrum analyzer and an electrical spectrum analyzer. © 2011 Wiley Periodicals, Inc.
